If electrons are much lighter compared to protons and neutrons, what can you say about the mass of an atom.​

Sagot :

Answer:

Atomic weight, further called relative atomic mass, it is the quantity of matter contained in an atom of an element. Research perceives that since 1961, the standard unit of atomic mass has been one-twelfth the mass of an atom of the isotope carbon-12. It is also proven that electron is much lighter than neutron. In fact, the mass of an electron is only 1/1837th the mass of a proton or neutron, thus electrons contribute virtually nothing to the total mass of an atom.
