An element's atomic numberis equal to the number of protons in the nuclei of any of its atoms. The mass number of an atom is the sum of the protons and neutrons in the atom. Isotopes are atoms of the same element (same number of protons) that have different numbers of neutrons in t...
-atomic weight is the average weight of an element, with respect to all its isotopes and their relative abundances- atomic mass is the mass of a single atom. Determining the number of subatomic particles proton# = atomic#neutron# = atomic mass- atomic# or (p+n)-pelectron# = ...
atomic number the number of protons in all atoms of a specific element mass number the weighted average of the masses of the different isotopes of an element atomic mass the mass of an atom of a particular isotope of a particular element; equal to the number of protons plus the number of...
