Interpretation Introduction

Interpretation:

The group and period of osmium element are to be determined.

Concept introduction:

The chemical elements are arranged in a column according to the increasing order of their atomic size, electron configuration, and their repeating chemical properties. This tabular form of arrangement of elements is called the periodic table.

These columns in the periodic table are called groups, and the rows are called periods. There are $18$ groups and $7$ periods in the periodic table.

The group and the period of a periodic table can be determined with the help of electron configuration.
