That's going to be somewhere in the neighborhood of 0.00054 .
About 1,840 electrons have the same mass as one neutron or proton.
So, in the largest naturally occuring atom ... Uranium ... with 92 electrons,
the electrons don't even contribute 1 count to the mass of the whole atom.

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.
When calculating an atomic approximate mass how is the mass of electron figured?
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.
When figuring atomic mass the mass of is ignored?
the electron is ignored
What is the difference between isobar and isotope?
isobars are elements with same mass numbers (Atomic Mass) and different atomic number (number of proton or electron)

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.
What is the atomic mass or weight of an electron?
electron mass = 9.10938188 × 10-31 kilograms = 0.000548579867 atomic mass units
Is atomic mass electrons?
We are not using electron mass. We measure atomic mass by Mass of neutrons and protons.
What is the atomic mass of an electron?
an electron is about 1/1836 amu.
When calculating an atomic approximate mass how is the mass of electron figured?
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.
In atomic mass unit what is the mass of an electron?
About 1/1836.
What is the Ce electron mass?
The atomic mass of "Ce" is 140.116
When figuring atomic mass the mass of is ignored?
the electron is ignored

isobars are elements with same mass numbers (Atomic Mass) and different atomic number (number of proton or electron)
How do you calculate the number of proton neutron and electron using atomic no and mass no?
atomic # = protons atomic mass - atomic number = neutrons atomic # - charge = electrons
What is the atomic particle whose mass can be ignored?
Electron
