Step-by-step explanation:

Elements are arranged in the increasing order of atomic numbers.

Elements in the modern periodic table are arranged in 7 periods and 18 groups.

Horizontal rows are called periods and vertical columns are called groups.

Elements are placed in periods based on the number of shells in their atoms.

The shortest period is the first period which contains only two elements – Hydrogen and Helium.
