Concept Introduction :
From the given set of isotopes of an atom, the most abundant isotope will have maximum percentage abundance.
(c)
Interpretation:
The number of neutrons in Sr-84 needs to be determined.
Concept Introduction :
The atomic number represents the number of electrons revolving round the nucleus in an atom. It also represents the number of protons in the nucleus of an atom.
The sum of the number of neutrons and protons in the nucleus of an atom represents mass number.
