$\huge{\pink {\sf\underline{Isotones:-}}}$

Isotone, any of two or more species of atoms or nuclei that have the same number of neutrons. Thus, chlorine-37 and potassium-39 are isotones, because the nucleus of this species of chlorine consists of 17 protons and 20 neutrons, whereas the nucleus of this species of potassium contains 19 protons and 20 neutrons.

$\huge{\pink {\sf\underline{Isoelectronic \: Species:-}}}$

Isoelectronic species are elements or ions that have the same, or equal number of electrons. This module explores that although isoelectronic species have the same number of electrons, they are different in their physical and chemical properties.

$\huge{\pink {\sf\underline{Electronic \: Configuration:-}}}$

In atomic physics and quantum chemistry, the electron configuration is the distribution of electrons of an atom or molecule (or other physical structure) in atomic or molecular orbitals.This is also useful for describing the chemical bonds that hold atoms together.
