protons
One element differs from another element by the number of protons in their atoms. The number of protons in the atom is known as the atomic number. Also one isotope of an element differs from another isotope of the same element by the number of neutrons in their atoms.
atomic number of an atom is its own characteristic property,ie.the number of protons or electrons in an atom,which distinguishes atoms from one another
Neutrons
An atom of an element that differs in the number of neutrons compared with other atoms in the same element is called an isotope. Isotopes have the same number of protons and electrons but different numbers of neutrons, resulting in variations in atomic mass.
Atoms of the same element with varying numbers of neutrons are isotopes.
Is called an Isotope.
This atom is called isotope.
