Question

What is diffrence between qn atom of hydrogen and molecule of hydrogen

Answer 1

Dear student,

H = Atomic Hydrogen

Atomic hydrogen is number 1 on the Periodic Table of Elements. It consists of one proton and one unpaired electron which means that it is a free radical. However, an atom of hydrogen rarely exists on its own because its unpaired electron eagerly seeks to join up with another electron.

The molecular form of hydrogen is more common.

H₂ = Molecular Hydrogen

H₂ is a gas that forms when two hydrogen atoms bond together and become a hydrogen molecule. H2 is also called molecular hydrogen. It consists of two protons and two electrons. Consequently, it is the most common form of Hydrogen because it is stable with a neutral charge. H2 is not a free radical. It is the antioxidant in ‘hydrogen-rich’ water.
