Question

4. Does an atom of an element always have the same number of neutrons as other atoms of the same
element? Explain your answer.

Answer 1

Explanation:

No. Isotopes are atoms of the same element with different atomic masses (due to the different number of neutrons)

For example, carbon exists as carbon-12 and carbon-14, which both have 6 protons but have 6 and 8 neutrons respectively.
