Answer 1

• The modern periodic table is an arrangement of all the elements known in accordance with their increasing atomic number and recurring chemical properties.
• It is a tabular display of the chemical elements which consists of horizontal rows called periods and vertical columns are called groups.

The shortest period in the modern periodic table is the first period which has only two elements that are Hydrogen $\left(\mathrm{H}\right)$ and Helium $\left(\mathrm{He}\right)$.
