Concept introduction:
An atom is made up of three subatomic particles-neutrons, protons, and electrons. Neutron and protons are present in the nucleus of the atom, whereas electrons are revolving outside the nucleus in an atom. The electrons are arranged in the orbit of atoms according to their energy.
(b)
Interpretation:
Whether the statement, “All atoms of a specific element have the same number of protons” is true or false is to be stated. If false, the statement is to be re-written.

Concept introduction:
If two atoms of an element have a different number of neutrons in them, then they are considered as isotopes of each other. The mass number of each isotope is different from the other. The mass number of an isotope is known as its isotopic mass.
(d)
Interpretation:
Whether the statement, “The mass number of an atom is always equal to or larger than the atomic number” is true or false is to be stated. If false, the statement is to be re-written.
