Question
Give reason: Hydrogen $(H2)$ molecule is also referred to as dihydrogen.
✓
Answer
The nucleus of a hydrogen atom consists of one positively charged proton i.e., nuclear charge of $+1$ and one extranuclear electron.
As this electron is in direct influence of nuclear attraction, hydrogen has a little tendency to lose this electron.
However, it can easily pair with the other electron forming a covalent bond.
Therefore, it exists in diatomic form as $H_2$ molecule and hence, it is also referred to as dihydrogen.
