Answer 1

Neutrons

Explanation:

Atoms of the same elements are called isotopes. They differ from other atoms in the number of neutrons they posses. They share the same chemical properties but only differ with regards to their mass number.

• Isotopy is a phenomenon whereby an atom of an element exist in more than one form but they have the same atomic number.
• Atoms of such element only differ in the number of neutrons they contain.
• Since the mass number of an atom is the sum of protons and neutrons, they differ in this number too
• Isotopes have the same chemical properties.
