Alpha decay | Physics | Khan Academy

[@jimboase5005]

Another great video. I studies Physics, Chemistry and Maths at university many years ago but have forgotten most of it through lack of practice since then. These videos have renewed my interest in it.

I'm learning about this in school this week!! This is perfect!! 🤩 thanks so much Khan Academy

[@smartiespot178]

Awesome Sir

[@StellaNamonje-rh3bv]

Am getting it❤❤❤❤❤😊😊😊

[@ankurec10]

So is alpha decay basically a way to get electricity without burning fossil fuels?

[@simplicityd8703]

And gamma is pretty much just energy

SCIENCE IS THE BEST

rope pls arjun

[@ikechukwukelvin3830]

Can you explain how the helium nuclei pick up electrons to become neutral atoms 9:22

[@carlosvellu1744]

I'm just curious where the strong nuclear force came from ..I know it's an attractive force but how did it came to be at the first place.

You know the atomic mass of a particle is some grams more than the real mass which is the addition of the mass of protons and neutrons in that particle.example: if the atomic mass of the particle is 28 grams but the real mass could be 27.28 grams.that means it is .02 gram less.this .02 gram is used in E=mc² where m means that .02 gram mass.thus this mass can create a great force which is the strong nuclear force (hope u understand😅)

Love u FloatHeadPhysics @Mahesh_Shenoy. Your videos are amazing.

Well my smoke detector goes off without any smoke, I guess it's past its shelf half-life xD I mean, for such an overkill complex system, you'd expect it to perform better, I just thought it was an interrupted electromagnetic beam that sounded the alarm...

[@sciencenerd7639]

hooray chemistry!

[@sinekonata]

Nuclear "chemistry" is still physics, chemistry deals with interactions around coulomb's forces.

[@sciencenerd7639]

@@sinekonata yes, I know that, this was obviously a comment for al gore's rythym

[@SharayuMulay2396]

But if the electron number is not changing then how is the atomic number changing? I don't really get it

[@QuinnOfhat]

I think atomic number is derived only from the number of protons n neutrons.

[@christinejackson6630]

Atomic number is the number of protons. The number of electrons around the nucleus is irrelevant for atomic number (protons) and mass number (protons + neutrons).

[@SharayuMulay2396]

Okay thanks I got it :)

[@localnoobanimator7732]

Electrons are sooo muchoghter than protons so they don't really matter much

[@itshayess]

first

Yo don't inhale smoke detector fumes That thing kills man ☢️☢️☢️☢️☢️☢️☢️☢️☢️☢️☢️☢️☢️☢️☢️🥑 Yoo don't do that last part i inserted the smoke detector in my nose it almost killed me
