A
valence
B
chemical bond
C

D
isotope
Explanation: 

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.

Detailed explanation-2: -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.

Detailed explanation-3: -As mentioned above, isotopes are different forms of an element that have the same number of protons but different numbers of neutrons. Many elements-such as carbon, potassium, and uranium-have multiple naturally occurring isotopes.

Detailed explanation-4: -Isotopes are the atoms of the same element; they have the same atomic number but different mass numbers. Isotopes have a different number of neutrons in their nucleus.
