Answer / r.raja
electrons are moving around the orbit of the atom.According
to Heisenberg prniciple position and momentum(P) of a
moving particle cannot be determined simultaneously at one
instance. since mass is to be determined from the formula m
= P/v, where P is the momentum and v is the velocity of the
electron.even if we can able determine the velocity we
can't determine the momentum at that time. hence the mass
can't be determined.hence it is negleced from the atomic
mass calculation.

Answer / .l.
We emit electrons from mass calculations because an electron has a relative atomic mass of approximately 1/1836, whilst protons and neutrons both have relative atomic masses of 1. We do not include the masses of electrons because it would make such a small difference the the mass of the molecule being measured.
