What can differ among atoms of the same element?

• Number of protons

• Number of neutrons

• Number of electrons

• Number of nuclei

What term is used to describe different versions of the same element?

• Isomers

• Isotopes

• Molecules

• Ions

Which of the following is true about isotopes?

• They have different numbers of protons
