Isotopes are atoms that have the same atomic number but different mass numbers.

Show answer

True

Isotopes are atoms of the same element with the same number of protons (same atomic number) but different number of neutrons (different mass numbers).

3multiple correct

Which of the following statements about noble gases are correct?

Show answer

They have complete outermost electron shells, They are chemically inactive

Noble gases have complete outermost shells (8 electrons except helium which has 2) making them stable and chemically inactive. They don't readily form compounds.

4multiple choice
