Question

How do isotopes differ in atomic structure?

Answer 1

Isotopic elements have same atomic number but different mass number.

For example, an isotope with 6 protons and 6 neutrons is carbon-12 or C-12. An isotope with 6 protons and 7 neutrons is carbon-13 or C-16.

Answer 2

Ans -

Isotopes are atoms of the same element. Remember that an atom is made up of three important components: neutrons, protons, and electrons. Isotopes of an element will contain the same number of protons and electrons but will differ in the number of neutrons they contain. In other words, isotopes have the same atomic number because they are the same element but have a different atomic mass because they contain a different number of neutrons.
