Question

The mass of an electron is _____ . a) 1/1840 b) 1 c) Negligible d) None of these​

Answer 1

Answer:

The electron, by comparison, has a mass of roughly 1/1840 the mass of either a proton or a neutron. Note that we have shown mass in both grams and atomic mass units (also known as relative atomic mass). One atomic mass unit (u) is defined as one-twelfth of the mass of an unbound neutral atom of carbon-12.
