Calculation of the nuclear binding energy and mass defect

preview_player
Показать описание
Calculate the mass defect and binding energy per nucleon for a lithium nucleus ( ^7_3 𝐿𝑖):
Mass of the lithium nucleus 𝑀 = 7.0 𝑢
Mass of the proton 𝑚𝑝 = 1.007825 𝑢
Mass of the neutron 𝑚𝑛 = 1.008665 𝑢
1 𝑢 = 1.6605 ∙ 10^{−27}𝑘𝑔 = 931 𝑀𝑒𝑉.

How did yoy converter from joules to Mev

from where do you find the masses that you put on the table

How can the energy of a chemical element be calculated from its electron configuration instead?

You can multiply the mass defect by 931.5 then divide by A to cut short, instead of converting to Kg then J

how are you writing this backwards and with your left hand bro like what

when did he incorporate the mass of electron in change of mass

Do you have to work in kg or can you multiply by 931.49 MeV/ u

I swear he smoked a pot right before making this video

the video was nice. but could you more examples? Because this one was very straightforward and not very challenging...

You say the mass of proton is 1.007825 amu.
Google says the mass of proton is 1.00727647 amu.
With that value, BE comes out to be 37.673MeV which way off than your value of 54.28 Mev.

WHICH ONE IS CORRECT?!? And what's wrong?

I'm a little hazy on how you converted Joules to MeV. Do you have another video explaining how this is done?

How he get the 54.28 MeV please explain it in more likely to a dummy dumdum like me
