Question

Hydrogen molecule is represented as:

• A. 2H
• B. H
• C. ${\mathrm{H}}_2$
• D. ${\mathrm{H}}_3$

Answer 1

The correct option is C

${\mathrm{H}}_2$

The explanation for the correct option:

Hydrogen:

• Hydrogen is a chemical element having an atomic number equal to one.
• It was discovered by Henry Cavendish.
• It has 1 proton and 1 electron in its only shell.
• So in order to complete its octet and acquire inert gas configuration one hydrogen atom combines with another hydrogen atom and they form a single covalent bond by sharing the 1-1 electrons each from both atoms and thus their octet gets complete.
• It exists in the diatomic form in nature so 2 atoms of hydrogen make one molecule H₂.

Therefore, option (C), is correct as Hydrogen exists in diatomic form (${\mathrm{H}}_2$).
