Two atoms A and B have the following composition:
AtomA, Atom B
17 protons,17 protons
18 neutrons,20 neutrons
What are their mass numbers? What is the relation between the species?

Text Solution

Verified by Experts

Mass number of A=17+18=35 ltrbgt Mass number of B=17+20=37
Tg atoms A and B represent a pari of isotopes since every have the same atomic number (17)
