Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Isotopes are elements that differ in the number of ____
A
neutrons
B
protons
C
electrons
D
neutrons and electrons
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. For example, carbon has six protons and is atomic number 6.

Detailed explanation-2: -The atoms of different isotopes are atoms of the same chemical element; they differ in the number of neutrons in the nucleus.

Detailed explanation-3: -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.

Detailed explanation-4: -More About Isobars It will have the same number of nucleons. The number of protons and neutrons alone will vary but the number of nucleons or the sum of protons and neutrons in isobars will always be same. Isobars always have different atomic structure because of the difference in atomic numbers.
