Explain why the masses of atoms of the same element may differ

Hello!

each element atom has a certain number of protons, which weigh 1 AMU, but the same element can have a different number of neutrons (weighing 1 AMU), which results in what is called an isotope

Normally, the atoms contain the same amount on neutrons. However, sometimes they gain more neutrons, which increases the atomic mass by 1 AMU for each additional proton.

I hope this helps, and have a nice day!

are you like autistic or something?

hi,

what occurs during a solar eclipse?

there are small tides across earth.

the moon is between earth and the sun.

p.s. im not sure if the first answer is correct because during a solar ecliphse there are spring tides and i dont know if they are the same.
