Question

The introduction of a neutron into the nuclear composition of an atom would lead to a change in

(a) The number of electrons also

(b) The chemical nature of the atom

(c) Its atomic number

(d) Its atomic weight

Answer 1

When we introduce the neutron into the nuclear composition of an atom, it would lead to change in the atomic mass of the atom. Atomic mass of an atom is defined as the sum of the number of neutrons and the number of protons in an atom.

So the introduction of a neutron into the nuclear composition of an atom would lead to a change in (d) Its atomic weight

Answer 2

Correct option is (d) Its atomic weight

Neutron is a chargeless particle and hence its introduction leads to increase in atomic weight.
