Question

What is the relationship between atomic number, mass number, isotopes, isobars and valency of atoms

Answer 1

Atomic number is considered to be the number of protons in an atom.
The mass number is taken as the total number of protons and neutrons present in an atom.
Isotopes can be defined as species of the same element with different mass number.
Whereas, Isobars are atoms of two different elements coincidentally happening to have the same mass.
Valency can be explained as the number of electrons capable of being active in a chemical reaction OR the number of electons need to gain/lose for the concerning atom to achieve and octate.

Answer 2

Answer:

Atomic number is the total number of protons present in an atom. Isotopes also mean atoms with same atomic number but different mass number. ... Also, isobars means atoms with same mass number but different atomic number. Whereas valency of an atom means the number of electrons present in the outermost shell
