What is the difference between an ion and an isotope?

• An ion has a change in number of electrons, an isotope has a change of number in protons.

• An ion has a change in number of protons, an isotope has a change in number of electrons.

• An ion has a change in number of neutrons, an isotope has a change in number of electrons.

• An ion has a change in number of electrons, an isotope has a change in number of neutrons.

What are the three sub-atomic particles

• Protons, Neutrons and Electrons

• Alpha, Beta and Gamma

• Huey, Dewey and Louie

• Sharon, Lois and Bram

If there are equal numbers of protons as electrons, we call this a(n)

• cation

• anion

• atom

If there are more protons than electrons, we call this a(n)

• cation

• anion

• atom

If an atom has 5 protons and 4 neutrons, then the mass number will be

• 9

• 5

• 4

• 1

If there are 3 protons, 3 electrons and 4 neutrons, this would be called

• Lithium-7 -1 anion

• Lithium-6 +1 cation

• Lithium-6 atom

• Lithium-7 atom
