      When I went to high school, the concept and understanding was different. We actually learned orbits, not orbitals, and electron position and notation wasn't as it is now.

      Hmmmm, what if the reason we can’t pin down the location of the electron is because it passes through 5 dimensional space. What we observe is the state of the electron at each snapshot in time.
      In the double slit experiment the electron takes all possible paths through to the target. We only know which path it takes if we observe it.
      What if that is why we can’t also pin down the electron orbital properly
      Our 4 dimensional world is a shadow of the 5 D world outside of ours. Just as the 2D world is a shadow of the 3D world.
      Our 4 th dimension, time, may be a shadow of the fifth dimension.
      Time itself seems one dimensional. It only goes one way, from our perspective. Top theoretical physicists say that there is no real reason why time could not flow backward.
      Maybe it does, we just can’t see, or observe it because we are one dimensional, we only observe the world in the forward arrow of time.
      An electron seems to transcend the physical,world taking al, possible paths through the two slits if not observed.
      Maybe the electron cloud,if observed properly, can give us a hint of what the fifth dimension may look like. Kind of like trying to observe a three dimensional world from the surface of a two dimensional shape.
      Just some thoughts.

      @@openwaters2988 Do a search for the "One electron universe", where theory suggests that every single electron is the same electron, that travels through space and time, to be in all places at once.
      It might go a little way to define further what you're saying.

    I think I teared up watching this. A) Because it was so complicated yet so simple and honestly so beautiful and mindblowing. We discovered this stuff! This is the universe! I'm surrounded bt this! And B) My teacher's've been constantly and REPEATEDLY trying to explain this to me - you know all the XYZ axes & stuff but there has NEVER been a proper visual for years & I never really grasped this concept. I didn't even know electrons moved randomly.
    I can't tell you just how thankful I am. Thank you!

      @Dr Deuteron İ perfectly understand your position. However you should note that most commenters here are not professional chemists or physicists but people who interacted with this material in high school or college. TBH my lecturers/teachers never presented the material in a way that would stimulate interest or understanding. I always wondered whether she understood the topic. The video has sought to simplify (maybe oversimplified) the material using analogies anyone would understand. That's why it has gotten such positive reviews from most commenters here. While I think that your efforts at providing detail are laudable, I believe that these efforts would be more useful if directed at encouraging teachers/lecturers in schools and colleges to better teach the subject matter. If they did, we probably wouldn't be having this discussion.

    I recall how I felt betrayed when after studying Thomson's plum pudding model, Rutherford's nuclear model and Bohr's orbital model in freshman high school and understanding that the electron is a particle of charge. Okay. Then we get to the senior year and we're told forget all of that an electron isn't a particle orbiting a nucleus but it is a cloud of charge surrounding the nucleus. Okay. Then I get to college and was told well its not a diffused cloud of charge but a probability of where the electron really is. 🤦‍♂️

      ​@@nihaal7750 Wrong is not really 100% correct either. It's just different shades of detail, some concepts are easier to understand if you use the simpler concepts of the atom. So that's why, the more you move into other subjects you will need more detailed (and more accurate) definitions of the atom for the other theory to make sense.

    These videos are awesome and stupendous. Thanks for these vivid illustrations. I wonder if you could provide similar videos on why these orbitals s p d f have such peculiar shapes in 3D space. To the extent I know, these shapes are the results of three-dimensional extensions of the different modes of vibrations seen for a particle stuck in between a one-dimensional potential barrier using the time-independent schrodinger equation. But to view the creation of these 3D shapes in process from the one-dimensional and two-dimensional modes of descriptions would not be less than an amazement. I hope your efficient team would be interested in such illustrations. More or less, I find my point on the same lines of the above comment.

    01:30 To state that an electron orbital is a "boundary surface" is almost as much a misnomer as it is to state it has an "orbit."
    A much better adjective would be a _probability cloud_ wherein the edge (or verge) of the cloud is not some rigidly defined boundary, but rather a region where the probability of detecting an electron drops off as you move away from the cloud region.

    Electrons negative charge must attract to the protons positive charge, don't they? Opposites attracts. However, an atom has electrons in different orbitals keep spinning around the positive charge nucleus which means opposites does not attract. Why the rule of opposites attracts does not apply in atoms?

    The electron orbital filling overlay on the periodic table changed my life. Where the hell was this in your classroom, Mrs. Kuhar!?!?!? I got through IB Chem 1 & 2 and never saw this.

    Nice illustration. However it it not explained here how you can derive the electron configuration WITHOUT the Mendellev (or periodic, if you prefer) table if you have the atomic number (e.g., 6 for Carbon). This is quite easy if you remember i) what is the maximum number of electrons per orbital type (s : 2; p: 6; d:10; f:14) and ii) a "number trick" that allows you to generate the number sequence that tells you the energy level (1, 2, 3, ...7). The number trick is the following. First, starting with 1 you must write each number the number of times it stand for (i.e., 1 should appear once, 2 should appear twice, 3 should appear 3 times, 4 should appear 4 times, etc.). Secondly, when you write the sequence, you must not stop on the same number as before but go one up : 1 (done, no more one after this), 2 (first time 2 appear, it should appear one more time), 2 3 (second time the 2 appears, cannot stop with 2 because already stopped at 2 at the previous step, so first 3 is introduced), 34 (second time the 3 appears, cannot stop with 3 because already stopped at 3 at the previous step, so first 4 is introduced; 3 will have to appear one more time), 345 (third and last time the 3 appears, cannot stop with 4 because already stopped at 4 at the previous step, so first 5 is introduced; 4 will have to appear two more times), 456, 4567, 567(8) (once you have to introduce 8, you stop). So, to recap : 1 2 23 34 345 456 4567 567(8). Once you are here, you add the orbital types, in their order: first s, then p, then d and finally f; this means only s for energy level 1, then for energy level 2 you have first s and then p, then for energy level 3 you have first s, then p, then d, and for energy levels 4 and above you have first s, then p, then d, and finally f. This yields: 1s 2s 2p 3s 3p 4s 3d 4p 5s 4d 5p 6s 4f 5d 6p 7s 5f 6d 7p. Example for C (carbon), with Z = 6: 1s^2 (so far 2 electrons, 4 to go), 2s^2 (so far 4 electrons, 2 to go) 2p^2 (stop at 6 electrons), so there you have it: 1s^2 2s^2 2p^2. The Ga example, with gallium having Z = 31: 1s^2 (so far 2 electrons, 29 to go), 2s^2 (so far 4 electrons, 27 to go) 2p^6 (so far 10 electrons, 21 to go), 3s^2 (so far 12 electrons, 19 to go), 3p^6 (so far 18 electrons, 13 to go), 4s^2 (so far 20 electrons, 11 to go), 3d^10 (so far 30 electrons, 1 to go), 4p^1 (stop, we have placed the 31 electrons), so there you have it for Ga: 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^1. If you have an ion, you must first determinate the number of electrons, starting from Z; for instance for Ca^2+, you have Z - 2 electrons, with Z for Ca being 20. This means there are 18 electrons for Ca^2+, so its electron configuration is: 1s^2 2s^2 2p^6 3s^2 3p^6.

    If 's' orbital is spherical in shape as we considered, then the electron can be anywhere inside the sphere in random motion.. then how do we conclude that the electron is moving around the nucleus in circular path possessing an magnetic moment...??

    Hünd's "rule" is more of a guideline than a hard-and-fast rule. The environment in which an atom or ion finds itself can dictate the relative energy of the one-electron-per-orbital versus the multiple-electrons-per-orbital state.
    An obvious example is the Fe3+ ion, which can exist in two separate spin states : three 3d electrons each in its own orbital, and two vacant orbitals; or an electron pair in one orbital, a lone electron in another, and three vacant orbitals. The shift from one to the other can be observed spectroscopically (commonly by using difference spectrometry). If the iron ion is constrained in a tetrapyrrole structure such as haem, this shift can be induced when an oxygen molecule coordinates with the iron.

    I think the double slit inerfierence patern can be well calculated if using the magnetic fields of the atoms of the slits and air atoms. Is this something that was tried to calculate with formulas including magnetic and energy flow... the glowing radiation de every corp emits, that will pass as a wave through both slits and influence the behaviour of the particule that pass by only one of both slits... without mesuring we could predict the behaviour with math.
