Identify the isotopes and isobars from the following list of atoms with given number of protons and neutrons.
`A:8p+9nB:8p+8nC:18p+22nD:20p+20n`.

Text Solution

Verified by Experts

A and B have the same number of protons but different number of neutrons. Hence A and B are isotopes. C and D have different number of protons, but the sum of the protons annd neutrons, in both the cases, are the same. Hence, C and D are isobars.
