The mass of an electron is almost entirely negligible compared to the mass of an atom. I'm not sure if that's the question you were asking, but you can essentially ignore electron mass when calculating the mass of an atom; an electron's mass is only about 0.0005 amu, so even for the heaviest elements the total mass of the electrons is still a tiny fraction of an amu.

What does the atomic mass of an electron represent?
The mass of an electron is atomic mass units is 5,485 799 090 70(16); the mass of the electron is not an atomic mass.
What is an electron's atomic mass number?
The electron has no atomic mass number. The mass of an electron is roughly 1/1800 of the mass of a proton or neutron.
How does the mass of a proton compared to the mass of the electron?
The proton mass is about 2,000 times greater than the electron mass.
What is the mass of 1 electron?
1/1836 of an electron is the mass of an electron. It is so small they aren't even calculated in the Atomic Mass of an element
Which has a greater mass an electron or a proton?
In kilograms, an electron's mass is ~9 x 10^(-31). A proton's mass is ~1.7 x 10^(-27). The mass of the proton is more than 1000 times of an electron.
What part of the atom does not add mass to it?
The electron.
Which component of an atom does not add to the atoms mass?
electron
What happens when you add an electron?
In this case the atom become an anion with the charge -1.
What happens to ionic radius if you add an electron?
Adding an electron to an atom increases its negative charge, leading to an increase in electron-electron repulsions. This results in the outer electron shell expanding, causing the ionic radius to increase.
What does the atomic mass of an electron represent?
The mass of an electron is atomic mass units is 5,485 799 090 70(16); the mass of the electron is not an atomic mass.
What is an electron's atomic mass number?
The electron has no atomic mass number. The mass of an electron is roughly 1/1800 of the mass of a proton or neutron.
