Justify the position of hydrogen in the periodic table on the basis of its electronic configuration.

Text Solution

Verified by Experts

Hydrogen has atomic number 1, with 1 electron in its valence shell. Thus, it exists in the first group and `1^(st)` period of the periodic table. Hence it is the first element of the periodic table.
