Concept introduction:

The elements in a modern periodic table are arranged in increasing order according to their increasing atomic numbers. In the modern periodic table, the horizontal rows are known as periods, and the vertical columns are known as groups. There are $7$ periods and $18$ groups in a modern periodic table. They are categorized into groups based on the type of energy sublevel that the last valence electron of the element enters.
