Now this a spectacular way to teach what radioactivity is . The systematic logic made it so interesting and easy to understand . thank you

After watching this video: “you know I’m something of a nuclear scientist myself.”

well done! i always look forward to your videos :)

Awesome video. Best I've seen so far 👏

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

Great explanation! Radioactivity explained in simple way that anyone can understand it. Thanks!

You made it so simple. Thanks!

Thanks bro you explanation is so simple

Easy to understand, well I alredy knew this, but I think anyone can understand it!

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.

Amazing 👏 sucks it took me till I was 30 to gain an understanding on a topic "taught" to me in highschool

Nicely explained

thanks for the detailed video, the beta Particle that deflected, in the magnetic filed(will it be Beta minus or meta plus?)

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?

You should do an audiobook on this topic... this is all really fascinating

very well explained thank you

Woah this was very helpful thank you so much for this video

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)

This video has been useful.

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?

Trying to create a manga power system that focuses on radioactive powers so I’m doing a TON of research.

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

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 ?

Very useful Thank you

Concept clear 👍👍

Lit video 🙏

Thank you

Thank you! My 7 year old asked about how the get electricity. Which led down a rabbit hole about nuclear energy.... radiation.... Chernobyl...

I have enjoyed

Shhhh, Man speaking.

Why is lead stable and realeses almost no radiation when number of neutrons is much more than protons

Yes it is that

I don’t understand almost half of this but I love this kind of stuff

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!

If you define the word nuclei before starting your explanation, you will have tons of more people understanding and watching the whole video.

Origins of evolution

does radiation explain why my left ear is hearing more than my right?

Cool but isnt it dangerous to hold uranium in hands if its that radioactive?

"what is radioactivity?" *raises hand* a song by kraftwerk, duh! ;)

In 16:13 I guess you're talking about neutron not proton

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.

High as in "High School" or high as in smokey smoke.

Are we just going to ignore the fact that he just handled a plastic container without safety goggles?

It’s in the air for you and me

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

🎉 good effort but too slow im falling asleep to your voice eh🎉

i had to stop it made me sleepy

This is confusing I’m here because of the Marshall island 🏝️

6:22 you drew your plot the wrong way around

I am more confused now than before I watched this, no help whatsoever

A good teacher always talks slowly and clearly. You speak too fast. Most people cannot absorb fast speech and learn.

Too complicated.

No way I’m watching a 25 minute video just to know what radioactive is, LIKE WHY CANT YOU MAKE A 1 MINUTE VIDEO AND SIMPLY SAY WHAT RADIOACTIVITY IS?!?
