How to tell protons neutrons mass numbers atomic weights from periodic table?
atomic weights is usually the number that has decimal points. so whenever you see a number with decimal point on periodic table, then that is the atomic mass.
Why atomic mass is always a whole number but atomic weight may be a decimal number?
Atomic mass of isotopes is not a whole number.
