NURSING ANM AND GNM

Detailed explanation-1: -Isotopes of a given element contain different numbers of neutrons, therefore, different isotopes have different mass numbers.

Detailed explanation-2: -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.

Detailed explanation-3: -The atoms of different isotopes are atoms of the same chemical element; they differ in the number of neutrons in the nucleus.

Detailed explanation-4: -Isotopes. An isotope is one of two or more forms of the same chemical element. 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-5: -the number of protons in all the atoms of a particular element is same, therefore to have different mass numbers, isotopes contain different number of neutrons.
