Detailed explanation-1: -Isotopes are members of a family of an element that all have the same number of protons but different numbers of neutrons. The number of protons in a nucleus determines the element’s atomic number on the Periodic Table. For example, carbon has six protons and is atomic number 6.
Detailed explanation-2: -Different isotopes of an element have the same number of protons in the nucleus, giving them the same atomic number, but a different number of neutrons giving each elemental isotope a different atomic weight.
Detailed explanation-3: -Carbon-12 and Carbon-14 are isotopes, both the atoms have the same number of protons (same atomic number i.e., 6) but have different mass numbers i.e., they differ in the number of neutrons.
Detailed explanation-4: -Isotopes of any given element all contain the same number of protons, so they have the same atomic number (for example, the atomic number of helium is always 2). Isotopes of a given element contain different numbers of neutrons, therefore, different isotopes have different mass numbers.
Detailed explanation-5: -The atomic number is the number of protons in an atom, and isotopes have the same atomic number but differ in the number of neutrons.
