Question

Hydrogen occupies a unique position in Modern Periodic Table.

• A. True
• B. False

Answer 1

The correct option is A True

Hydrogen has electron configuration of $1s^1$.To become stable it can either accept to get helium configuration that is a stable configuration or it can even donate one electron. Hence it is very confusing where to place either in the metals group as it donates or in nonmetal group as it accepts an electron. Hence it occupies a unique position in the periodic table.
