Question

Neutrons are present in the nucleus of all atoms, except-

A.

Hydrogen

B.

Carbon

C.

Oxygen

D.

Nitrogen

Correct option is A


Out of the given options, only the hydrogen atom typically does not have a neutron in its nucleus. Most elements have at least one neutron in their nucleus for stability, but the simplest element, hydrogen, can exist in a stable form with just one proton and one electron (no neutrons). There are, however, isotopes of hydrogen with neutrons, but the most common form (Hydrogen-1) does not.
