How many neutrons are present in the Hydrogen atom.

Symbolic representation of Hydrogen atom:

• The hydrogen atom is represented as ${\mathrm{H}}_1^1$
• The No. of neutrons can be calculated as (n) = Mass number(A) - Atomic number(Z)
• Atomic number (Z)=No of neutrons(n)+No of protons(p)
• The atomic number(Z) of Hydrogen = 1The mass number(A) of Hydrogen = 1

Therefore, No. of neutrons in Hydrogen atom = 1 - 1 = 0 neutrons
