(a) What are the mass numbers and atomic numbers of A and B?
(b) What is the relation between the two chemical species?
(c ) Which element or elements do they represent?

Text Solution

Verified by Experts

(a) Mass number of A=17 + 18 = 35 u
Mass number of B= 17+20 = 37 u
(b) The two chemical species exist as pair of isotopes since they have the same number of protons and electrons ltbr (c ) They reperesetn the element chlorine (CI)
