Which of these is NOT a subatomic particle?

• Protons

• Neutrons

• Electrons

• Ions

Which subatomic particle has a neutral charge?

• Neutrons

• Protons

• Electrons

• Alpha and Beta Radiation

Electrons are located inside the nucleus

• True

• False

This subatomic particle is responsible for how an atom behaves

• Protons

• Neutrons

• Electrons

On the Periodic Table Groups:

• Are verticle and tell us the number of valence electrons

• Horizontal and tell us the number of valence electrons

• Are verticle and tell us the number of electron shells the atom has

• Are horizontal and tell us the number of electron shells an atom has

Atoms are organised on the Periodic Table. Periods are arranged...

• Horizontally

• Vertically

Each element has a Mass number. This tells us;

• The number of protons

• The number of electrons

• The number of protons and neutrons

• The combined number of subatomic particles

What is the atomic number of an atom that has 3 protons, 3 electrons and 3 neutrons?

• 3

• 6

• 9
