• A Large Atom

• A Small Atom

• A Cute Atom

Barium atoms want to form...

• an anion

• a cation

• an onion

• a cuddly kitten friend

Why are ions formed?

• To make our lives difficult

• Because atoms want 8 valence electrons

• Because atoms have the same number of protons and electrons

• Because atoms gained neutrons

An atom becomes _______ when it loses electrons.

• Positive

• Negative

• Neutral

• Invinsible

A Silicon atom wants...

• 3 more electrons

• 3 less electrons

• 4 more or less electrons

• 2 more electrons

A Radium atom wants...

• One more electron

• One less electron

• Two more electrons

• Two less electrons

If an atom gains electrons when forming an ion, the charge will be:

• positive

• negative

• neutral

Why do atoms ionize?

• To achieve an octet of valence electrons.

• To achieve a lower energy state.

• To stabilize electron energy states.

• All of these are correct.
