Question

Explain the need for a reference atom for atomic mass. give some information two reference atoms.​

Answer 1

Answer:

Atomic mass is the is the sum of the electrons and the neutrons in the atom. Number of electrons is the atomic number. Hence to determine the atomic mass the reference of the atom is required. Example to find the atomic mass of atom magnesium Mg we need to know the atomic number of magnesium.
