Atom A has a mass number 209 and atomic number 82.Atom B has a mass number 209 and atomic number 83.(i) How many protons atom A has ?(ii) How many protons atom B has ?(iii) Are atoms A and B isotopes of the same element ?
Atom A – 20982A
Atom B – 20983A
(i) A has 82 protons as the atomic number is 82.
(ii) B has 83 protons as the atomic number is 83.
(iii) A and B are not isotopes of each other because their atomic numbers are not same.
