Front

What is the mass number of an isotope?

Back

The mass number of an isotope is the total number of protons and neutrons in its nucleus.

Front

How do isotopes of the same element differ?

Back

Isotopes of the same element differ in the number of neutrons, which affects their mass number.

Front

What is the atomic number of an element?

Back

The atomic number is the number of protons in the nucleus of an atom, which determines the element's identity.

Front

If two isotopes have the same mass number but different atomic numbers, what can you infer about them?

Back

They are not isotopes but different elements.
