Question

Change in the number of neutrons in an atom changes it to
a) an ion. b) an isotope.
c) an isobar. d) another element.

Answer 1

B) An isotope

IS THE CORRECT ANSWER

Answer 2

When you change the number of neutrons in an atom, It changes to an isotope.

Changes in number of neutrons doesn't affect the number of protons or electrons , Hence The atomic number remains same.

As neutrons are added or removed, Mass number changes .

Two atoms of same element having different mass number are also called Isotopes.

Hence, When you change the number of neutrons in an atom, then the atom changes to an isotope of the earlier one.

Required option : B, An isotope.
