What happens when you add an electron to its mass?
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 is a particle of relatively negligible mass?
An electron, with relatively negligible mass meaning the mass of an electron is so insubstantial that it isn't counted towards the total weight of the atom.
What is the electron mass an atom?
an electron is about 1/1836 amu.
Which particle of an atom has the less mass?
The Electron.
What is the difference in mass of Na ion and Na atom?
The difference in mass between a sodium atom and a sodium ion (supposing Na+) is 9.10938188 × 10-31kg (the mass of an electron). This is due to the sodium atom losing an electron to form an ion. In order to attain the mass of a single sodium atom you need to divide the molar massn (mass number) of sodium by avogadro's number. You can then find the mass of the ion by subtracting the mass of an electron from the mass of a sodium atom.

Why does the nucleus contain most of the atom total mass?
This is because the mass of electron is without importance compared to the mass of protons and neutrons.
Which in an atom has the least mass in an atom?
Which particle? The electron.
What is the electron mass an atom?
an electron is about 1/1836 amu.
What sub atomic particle does not particitpate in the calculation of mass of atom?
Mass of electron is not included for the calculation of mass of an atom.
What part of the atom does not add mass to it?
The electron.
Which particle of an atom has the less mass?
The Electron.
Which particle has the smallest mass atoms or electron?
An electron has a much smaller mass than any atom.

What is the mass of an atom concentrated on?
virtually all the mass in concentrated in the nucleus of the atom, as the electron's mass is so small, it is negligible.
What is a subatomic particles with almost no mass?
The electron is the lightest particle in the atom.
