Which of the following describes an isotope?
A
same number of neutrons, different number of protons
B
same number of neutrons, different number of electrons
C
same number of protons, different number of electrons
D
same number of protons, different number of neutrons
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: -Deuterium also known as heavy hydrogen is one of the two stable isotopes of hydrogen. The nucleus of deuterium called deutron contains one proton and neutron. Was this answer helpful?

Detailed explanation-3: -Nuclei with the same number of neutrons but a different atomic number are called isotopes. Nuclei with the same mass number are called isotones.

Detailed explanation-4: -Isotopes are atoms of the same element that have different numbers of neutrons but the same number of protons and electrons.

Detailed explanation-5: -Explanation: In the field of chemistry, isotopes can be described as elements that have the same atomic number but different mass number.
