Why atomic mass is always calculated from number of protons and not from number of electrons?

Hello mate,

Here is your answer,

Atomic number is always equal to number of protons in an atom in its stable state and also equal to number of electrons.

No of protons=No of electrons=Atomic No.

But for ions or charged atoms the atomic number is equal to number of protons but not equal to number of electrons.

HOPE THIS HELPS UU :)

AND STAY BLESSED.


divyaakapoor6: My question isn't that. I asked why its calculated on protons and not on electrons?

When you talk about the atomic mass of a neutral atom, then there is nothing wrong in calculating the mass as the sum of number of electrons and neutrons. But when we calculate the mass of an atom's ion, then the number of electrons is variable but not that of protons.
This is one of the reasons of your query.
If it helps, you may give a moment to mark it the brainliest.
