Answer:
Option c, Each element has its own neutron number
Explanation:
Atomic number of any element is unique. All the atoms of an element have the same atomic number. Atomic number defines the identity of the element.
Atomic number is equal to number of proton. So, number of proton is also unique or each element has its own number of proton.
Chemical symbols are used to represent element in easiest way. Therefore, chemical symbol has to be specific for each element.
Atoms of an element can have different number of neutrons. Atoms of an element having same no. of proton but different no. of neutron are called isotopes.
So, among the given option, option c is false.
