Answer 1

Answer:

atomic no. is a no. which is equal to its protons

mass no. is sum of nutrons + protons

isotope = who has same atomic number but different mass no.

isobars = who has same mass no. but different atomic no.

Answer 2

Answer

Mass number is always an integer.

The atomic mass reported on a periodic table is the weighted average of all the naturally occuring isotopes.

Being an average it would be most unlikely to be a whole number.

The mass of an individual atom in atomic mass units is the mass relative to carbon-12.
