Question

define
valency,isotopes and isobars?​

Answer 1

Answer:

In chemistry, the valence or valency of an element is a measure of its combining power with other atoms when it forms chemical compounds or molecules.

Isobars

Species or atoms having same atomic mass number but different atomic number

For example - 146C, 147N

They have the same number of nucleons i.e sum of protons and neutrons are same but Number of protons and neutrons alone varies between them

isotopes are the elements of the same atom with different mass no
