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.
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.
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 the atomic mass of an atom, the mass of an electron is typically considered negligible. This is because the mass of an electron is almost 2000 times smaller than the mass of a proton or neutron, which are the primary components used in determining the atomic mass of an atom.
isobars are elements with same mass numbers (Atomic Mass) and different atomic number (number of proton or electron)
No, the mass of one electron is approximately 1/1836 times the mass of one atomic mass unit. The atomic mass unit is defined as 1/12 the mass of a carbon-12 atom, which is much larger than the mass of an electron.

electron mass = 9.10938188 × 10-31 kilograms = 0.000548579867 atomic mass units
We are not using electron mass. We measure atomic mass by Mass of neutrons and protons.
an electron is about 1/1836 amu.

About 1/1836.
