Stable and Unstable Nuclei | Radioactivity | Physics | FuseSchool

How do you know if an atom is stable? In this video we are going to learn about radioactive decay and that unstable nuclei either have too many protons or too many neutrons, which upsets the strong nuclear forces holding the atom together. Unstable nuclei try to balance themselves by giving off the excess proton or neutron either through alpha, beta minus or beta plus decay.

This video made it so much simple to understand radioactivity, thank you.

[lindaw]

The best explanation I've seen over the entire internet so far. Well done and thank you very much!!

[chefrederick]

Haven't understood this for ages and this video comes along and makes it crystal clear, Thank you much

[Autovetus]

Quality content. Im a bit Stoned and i needed explanation, and i found it .

[kusumav]

The visual lecture is very clear to understand and conceptually clear too... It helped me a lot. Thank you.

[priyanshadahiya]

Its the most easiest, understandable, authentic and genuine video that explains radioactivity in just 5 mins!! Not only this I just love the channel! Just a video brushes u with the complete concept ! I often use them before class to get an extra edge and if u are having trouble with revision, voila! Just a video from this channel and u have revised the entire concept!
Such a wide topic is covered in such a small time! Its just short crisp and precise!! Thank u fuseschool !! You have been a great great help!!
Thanks 💕🌸✨
Regards 😊
Priyansha!! :)

[loganpitts]

Needed this for my science test, thanks.

[luvmaima]

Talking a chemistry test tomorrow and needed someone to explain it more clear and looks like I got someone now 😁😁

[timothybeach]

Excellent concise overview! Thanks for putting all of this in a nutshell and making it easier to see the big picture!

[JH-rtco]

I am a biologist but work at a radiopharmaceutical company...this video was very helpful!

[sadiqshaikh]

Small. Concise. Direct. Clear.
This was pure amazing👍

[tatoemonkey]

This is brilliant, I'm studying for a health and safety diploma and you learn across the board so even though I dont work with radiation, never have, probably never will, I still need to learn about it and this explains it in clear and simple terms. Great job thanks for making my study easier.

[holdup]

thank you so much for this video. it's short and simple, but amazingly i understood this more than what i learnt in my 2hour radionuclide lecture

[sunnyclean]

Perfect vid for peeps struggling in chemistry thank you man I greatly appreciate it

[GalaxyOfMoses]

so incredibly helpful and easy to understand. the timestamps are great too. thank you so much!

[karhukivi]

Good explanation of the basics, radioactivity is a weight-adjusting phenomenon for the nucleus. In really large nucleii, i.e. above atomic number Z=90 (thorium) another decay method, fission, can happen spontaneously but it is very slow compared to the other decay modes.

[hopejensen]

Apart from the Big Bang part, extremely helpful and direct! Thank you!

[shreeyarahate]

This is just the best explanation ever thank you very much.

[charanmadhav]

Bruh this video is the best imma 10 years and I could understand each and everything in this vid thanks 🙏

[roronoazoro]

thia video needs a very genius brain that able to simplify radioactive this much thank you so much for your existence
