Atoms of the same element that have different mass numbers are called:

• Ions

• Isotopes

• Isomers

• Allotropes

The atoms have different mass numbers because:

• they have different numbers of neutrons.

• they have different numbers of electrons.

• they have different numbers of protons and electrons.

• they have different numbers of energy levels.

The number 17 tells you which two things about the structure of a chlorine atom?

• The number of energy levels and the number of neutrons

• The number of neutrons and the number of protons

• The number of protons and the number of electrons

• The number of electrons and the number of neutrons
