When calculating an atomic approximate mass how is the mass of electron figured?
Wiki User

The mass of electrons is ignored in calculating an approximate Atomic Mass, because an electron's mass is only about 1/1836.1 of the mass of a proton or neutron.

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.
Is there a correlation of electron affinities to atomic radii?
The relation between electron affinity and atomic radius is inversely proportional.
What is the atomic mass of dysprosium?
The atomic mass of dysprosium is 162.5, though that may just be approximate
Which sub-atomic particle cannot change?
The sub-atomic particles does not change is electron. Electron not remains negatively charged but its mass remains the same too.
