Just starting a degree in Radiotherapy. I don't understand this topic at all but I came across your video and has really helped me understand some stuff now. Love for the help and explanation
What happens to the chemical bonds of something that is decaying? E.g., polonium and lead have very different crystal structures and valance electrons. Would it create strain in the crystal structure?
Hello sir In the alpha decay of uranium 238 the newly formed element is also short by 2 electrons. Where do these electrons go in the process? Regards M Jafar
It converts into alpha particle and as we know number of neutrons = no of protons so when U238 undergoes alpha decay and emits Helium 2 4 which has two electrons hope this helps
Thank you very much, i surely won't be able to remember all but now i understand a little bit better what are radiations. I guess i'll come back to strenghen what i learn today. So i will be a little bit able to explain this to my children.
Thank you for the video. I don't understand one thing, let's assume that we had atom with mass number of 3 and atom number of 2, and If we know that in the beta decay mass number stays the same and only atom number changes, does that mean that the nuclei of the atom will never get to the stable state and we will have indefinite decay ? (I am pretty sure that I am missing something)
Random and spontaneous. Orbits are not random, but I guess they are pushed around by the vacuum fluctuations causing random event like radioactive decays. But where does this seemingly randomnes of the vacuum fluctuations really come from ? Is it comparable to brownian motion or the noise from electrons jittering around in a conductor ?
That's really a good question. after watching this video I think of 2 possible options: 1) the amount of protons and neutrons in new Pb atom is just enough for a strong force to keep it together. 2) It may be actually unstable for the first time but then there is some type of a gamma decay after so that in the end Pb will become a low energy Pb and then it's point 1 again - strong force can keep it together. I wonder how close am I though ?
@@Ninthofnine1969I'm 15 and already know the basics of quantum mechanics, nuclear physics, and astrophysics. UA-cam really is quite the learning tool.
I have a question. How come all models of an atoms nucleus for the exceptions if a few very light particles like alphas, deuterium, & protium show the nucleus as a jumble mess kinda like a plum pudding model applied to the nucleus. I highly doubt that to be the case. I think it also explains way a helium nucleus is the standard alpha particle. What does the tritium nucleus really look like in a 3D model at what opposing angles are these baryons at in that case and does it scale. Is this the key to isotope stability?
Great video. I don't understand why the radiation is dangerous though? Don't we already have protons and neutrons in our bodies already? Why do these particles cause harm? Thanks.
Because the radiation can penatrate deep into our tissue, and cause harm to the very fragile DNA.material and lead to very bad mutations. It can cause, and as. we know of nowx it does cause cancerand overall is just very destabilizing for our body's natural way of functioning.
People fear radioactivity too much. You respect it, like anything else. I imagine that since radiation is everywhere, that our bodies probably even depend on it to some degree, generating radicals and ionizing stuff, so if we isolated them from radioisotopes completely, might cells actually do worse or even get quite sick or die? Too little could be bad, much as too much is!
As far as I know humans emit radiation at a very tiny levels because radiation is also a type of energy and many of our day to day electrical appliances emit radiation at a minute level which doesnt effect our bodies. So what if we isolate our selves from radiation well life on earth evolved in the background of radiation without things woludnt go good for us.Hope this helps
I don’t see what’s wrong with the plot. It’s a graph of protons vs neutrons. For larger atoms, there tends to be more neutrons, so the graph will curve upward (since he has neutrons on the y-axis or vertical axis)

Thanks for making this video:)
I'm currently going through a mental breakdown, and learning about radioactivity calms me down a lot:3
Now this a spectacular way to teach what radioactivity is . The systematic logic made it so interesting and easy to understand . thank you
Thanks

Good luck mate ✌️
After watching this video: “you know I’m something of a nuclear scientist myself.”
?.
😂 😂 😂

Great explanation! Radioactivity explained in simple way that anyone can understand it. Thanks!
You’re welcome
Awesome video. Best I've seen so far 👏
well done! i always look forward to your videos :)
thanks for the detailed video, the beta Particle that deflected, in the magnetic filed(will it be Beta minus or meta plus?)
He says at 21:30 that it’s “not a positron”

Thanks bro you explanation is so simple
Easy to understand, well I alredy knew this, but I think anyone can understand it!
If you define the word nuclei before starting your explanation, you will have tons of more people understanding and watching the whole video.
You should do an audiobook on this topic... this is all really fascinating

Why is lead stable and realeses almost no radiation when number of neutrons is much more than protons
That's really a good question. after watching this video I think of 2 possible options:
1) the amount of protons and neutrons in new Pb atom is just enough for a strong force to keep it together.
2) It may be actually unstable for the first time but then there is some type of a gamma decay after so that in the end Pb will become a low energy Pb and then it's point 1 again - strong force can keep it together.

Because you’re not factoring in the electrons
Trying to create a manga power system that focuses on radioactive powers so I’m doing a TON of research.
Amazing 👏 sucks it took me till I was 30 to gain an understanding on a topic "taught" to me in highschool
Yep I'm 55 and I've learnt more from utube than I ever did at school 🎉🎉🎉

Keep waiting for an amswer

Thank you! My 7 year old asked about how the get electricity. Which led down a rabbit hole about nuclear energy.... radiation.... Chernobyl...
You made it so simple. Thanks!
Nicely explained
This video has been useful.
Woah this was very helpful thank you so much for this video
You’re welcome
very well explained thank you

@@uramijajlovic5444 thanks for the reply. Makes sense.
@@billybobhouse9559 Welcome! 😁 There's great research on the internet so you can search that up if it interests you.
Cool but isnt it dangerous to hold uranium in hands if its that radioactive?
Not for a very small time period also it is on a very small scale
Concept clear 👍👍
thanks
In 16:13 I guess you're talking about neutron not proton
I don’t understand almost half of this but I love this kind of stuff

Welcome 😊
does radiation explain why my left ear is hearing more than my right?
No
Radioactivity basically is like popcorn🥰
Shhhh,
Man speaking.
It that true all radioactive elements can emit all types of radiation
Thank you
Lit video 🙏
6:22 you drew your plot the wrong way around
How am I the only person who noticed?

"what is radioactivity?"

🎉 good effort but too slow im falling asleep to your voice eh🎉
So if beta radiation is for smaller atoms,i why Caesium 137 ended up producing beta decay and lefted positrons as a residue in Dark serie? hahahahaha
Yes it is that
In dental hygiene school.. why do i have to do this bs💀
