My chemistry teacher showed this to us during my junior year in high school in 2014

this is really helpful. Thank you, Mr. Bell!

Great video - thanks:)

I wonder what kind of stability blackholes and neutron stars may offer atomic nucleuses

cool

I always laugh when people say the four corners of the Earth. Its been long established that the Earth is neither flat or quadrilateral, but a sphere with a bit of a waistline. Nice documentary enjoyed it thanks.

I like these older ones Thanks

Why cant there be more than 18 groups?

thank you

You are the best, thank you so much for posting these videos they really are informative and give me clarity and helped my study.

thank you Bell

6:13 - error: there's a fault with the Keq equation where it's not balanced correctly, I though it should've been 2 H2. (g) + O2 (g) <-> 2 H2O(g).

this helped me with my test, very helpful, thank you!

Pls upload mcq discussion based pn this topic😊

good lecture with good explanations thank you very much

Seaborg sounds a bit like cyborg...

Outdated but interesting video. On comment. The.heavy.elements are neutron poor. As we go up in the periodic table the neutron to proton ratio goes up. These smash on atoms have similar neutron/proton ratios. That makes the atoms neutron poor. Plutonium238 has a half life of about 80years. It's perpetually hot. Uranium232 has.a half life of only 32 years. Add 3 neurons and you get U235 with a half-life of about 8x10^8 years. Add three more neutrons and you have U238 with a half life of 4x10^9 years. 😅

How is it propylamine @2:45? Shouldn't that be ethyl?

How old is the need video? It stops at Z=102, but Seaborgium was named in 1997 (Z=106).

2:52 The stars got past uranium, it's just all decayed.

mouldy video quality

Now neal should uncover the mystery of how wearing a muscle shirt alters your chromosomes to be precicsly 80% male? And a make-up does the same thing but female..... What are the mechanisms that the muscle shirt works on to have this effect? Is this a coincidence or is it a result of evolution and natural selection? Only the muscliest Of shirts will survive and pass their genes on.... Also, how did the muscle shirt survive the meteorite that made the dinosoars extinct? Seems obvious that the dinosaurs didn't survive because they hadnt evolved the instinctual knowledge of how to leverage the muscle shirts power.... dinosaur fossils are undeniable proof of this... just look at raptors or the t-rex and their puney girlyman arms.... noone with arms that puney wears muscle shirts! Unequivocal proof that the dinosaurs only went extinct cause they don't even lift bruh! Thank god neal doesn't have that problem tho! One time I heard that he put a muscle shirt on top of a muscle shirt and became 160% masculine. But it was too much muscle shirt for 1 astrophysicist who's gender is a fashion accessory, and he ended up astrobullying the smallest planet in the solar system and called him a dwarf planet, then kicked him out of the whole solarsystem..... If the dinosaurs could leverage all that muscle shirt masculinity and did some lifting, I dont think the meteorite that way smaller than Pluto would have stood a chance if decided to roll up on dem dinosaurs.... I rest my case! Trust the science!

4:38 🤣

Great joke for the segway to the second part of the video! It caught me so off guard

Is this real?

Wowza!

thank you

Thank you

where the heck is quantum mechanics in this ?

W

Wow! I never knew that the mole plan could be so flippin cool! Great teaching you got going on over there, keep up the great work!

thank you for the video, saving my chem mark

that is a good looking hand
