Interpretation Introduction

Interpretation:

Diamagnetic and paramagnetic atoms has to be determined among the first 18 elements from hydrogen to argon

Concept Introduction:

Electron configuration is the distribution of electrons in the atomic orbitals. It gives an idea about the shape and energy of electrons in an atom.

There are 3 rules to decide the electronic configuration of an atom. They are,

Pauli Exclusion Principle: No two electrons should not have same four quantum numbers in an atoms that is, it no two electrons should have same principal quantum number (n), same orbital angular momentum quantum number (l), the same magnetic quantum number (ml) or same spin magnetic quantum numbers (ms)

Aufbau Principle: In an atom, electrons fill according to the increasing energy of the orbital.

Hund's Rule: The orbital having maximum number of electrons with same spin in separate orbitals is the most stable arrangement in an orbital.

Paramagnetic compound contains at least one unpaired electron.

Diamagnetic compound does not contain any unpaired electron
