[@yayatistudios]

best explanation I have ever seen just the thing I was searching ...!!!

[@solafab424]

Thanks alot that really helped me!! I was struggling on this part I couldnt even understand a single word but after watching this video every thing passed so easy ❤❤❤❤❤❤

[@ddharsh2548]

Very clear and straight to the point, not too fast and clear visuals. Thank you so much!

[@fuseschool]

Thank you for watching!

[@afgclick6989]

That was brilliant thanks for that

[@fuseschool]

Thank you!! :-)

[@rrdz473]

Great video. Easy to understand and to the point. Thank you.

[@sandraelgizooli3098]

omg I did so good in my test because of this!

[@RenaRoll]

radioactive isotopes have never been explained better!!! Thank you!

[@fuseschool]

Thank YOU!

This video is amazing more than i expected

[@fuseschool]

Glad you liked it!

[@talhanazir341]

very comprehensive way to explain radioactivity reason. specially analogy of boxes is great Sir.

[@thangapandim3492]

great explanation

[@stephanielue8454]

omg i finally understand

Great video guys keep up the good work i learnt a lot

[@fuseschool]

Thank you! Appreciate it!

[@drjaara]

very helpful thank you a lot

[@fuseschool]

Glad it helped!

[@giulianafusco7039]

Thank you so much! I have a test tomorrow and I think I will actually do well! I finally get it :))))

[@fuseschool]

Hope it went well!!

[@vibewithsri8064]

That moment when the lady dropped her books and he said "you will achieve a stable state" was really helpful... THANK YOU💙💙💙

[@fuseschool]

You're so welcome!

[@misheelurtnasan4267]

Thank you so much!

[@annettedexter6614]

You state that deuterium is a radioisotope of hydrogen. This appears to be incorrect--deuterium is a stable isotope of hydrogen.

[@fuseschool]

You are correct; the teacher made a mistake. Thank you for spotting it. Deuterium is just an isotope, not a radioisotope.

[@fennwick9008]

Thank you!

[@fuseschool]

No problem!

[@rachelackman3028]

Thank you

[@beerus553]

Great Thanks For DEEEE HELP MisTa

[@theresaschuster9612]

Very informative

[@majdanasseir3860]

do we have to learn the isotopes for ig's like cl35 and all those numbers?

[@wissamadill4943]

thank you ...sooooo much ...👏👏👏👏👏👏👏👏👏😊😊

[@jeyakumarkalawathy3929]

Great

[@Apocalyptikai]

Wait, too many protons? Where do nuclides get more protons? I thought it was impossible for there to be more protons in an isotope?

[@fuseschool]

Hi. Which part of the video? Let me know the timing, and I'll have a watch to see if there's something wrong. But yes - isotopes are atoms of an element with the normal number of protons and electrons, but just with different numbers of neutrons.

[@Apocalyptikai]

At 2:13 its said that "if there are too many protons". I was curious, because I thought isotopes couldn't have more or less protons? I thought it was only neutrons that changed in amount, not protons.

[@fuseschool]

Great question, which I will try and explain the answer to. Some nuclei do not have enough binding energy to hold the nucleus (protons and neutrons) together. These are known as unstable nuclei, and are radioactive. Some unstable nuclei have too many neutrons to hold together, and so lose neutrons. Some unstable nuclei have too many protons to hold together, and so lose protons. The balance of protons and neutrons in a nucleus determines whether a nucleus will be stable or unstable. Too many neutrons or protons upsets the balance and disrupts the binding energy, making the nucleus unstable. An unstable nucleus tries to achieve a balanced state by given off a neutron or proton (by radioactive decay). But these aren't necessarily isotopes. Isotopes are just to do with neutrons... Isotopes are atoms of an element with the normal number of protons and electrons, but just with different numbers of neutrons. I hope that explanation was clear and helps?

[@Apocalyptikai]

Yes, it does. Thank you!

[@okiksapa1]

Okay I'm a little dense here so bare with me. If say a hydrogen atom had too many protons in its nucleus. wouldn't become a different element altogether? Like one more proton would make it helium?

[@breezyhayes9786]

Shout out to my fellow freshmen struggling

[@netorare3310]

are there any risks using radioisotopes?

[@akumaram]

So which isotopes are radioactive exactly? Or is it infinite? Also, is there a limit to the number of isotopes in an element?

[@majdanasseir3860]

i need the answer for the same question as you

[@GalaxyGirl1970]

I was under the impression that deuterium is a stable isotope of H.

[@fuseschool]

+GalaxyGirl1970 - it is a stable isotope, you are correct. We have made this edit and will be re-uploading the corrected version. Thank you for spotting this error!!

[@Apocalyptikai]

Where do nuclides get more protons? In the video its mentioned if a nuclei has too many neutrons or protons? I thought protons within isotopes were always the same set number (atomic number)?

[@AnonyTests]

slob room I think what they meant by more protons is that there are more protons than neutrons, and not the number of protons was changing. Too many neutrons = the number of neutrons is high Too many protons = the number of neutrons is low (making the protons appear to be more) The atomic number (protons) of an element changes when the element transforms to another element. Meaning if an atom lost or gained a proton it becomes a different element. If you add a proton to hydrogen, for example, it will become helium.

[@Mrslovetomatoes]

very good

[@fuseschool]

Thanks!

[@narusasu7279]

Wait, if radio isotopes are unstable, wouldn't they rearrange themselves such that they become stable again? My point being that won't radio isotopes last for a short period?

[@calebbengtson2714]

Yea they got something called a half life so for example cobalt 60 got a half life of 5.3 years meaning every 5.3 years it will decay by half

[@luisefang2449]

naru sasu you got more neutron than the proton and if you have more neutron in the neucleus it will be broken down and realesing radiation

[@janearkensaw4386]

Thanks so much! Fuck physics, but then again, _fuck_ physics, you know? You made it so simple to understand, will look forward to watching more!

[@kokfahchong1867]

Having too many neutrons within the nucleus could also be a threat to its stability which clearly shows that neutrons are not neutral at all. If you are interested in real discoveries, I would recommend you to read my book, The Unification Theory - Volume One and you will be amazed with lots of new, interesting discoveries. In God I trust.
