Ionic Compounds

Question 1

How are ions formed

Answer 1

-when atoms gain or lose electrons, giving them an overall charge

Question 2

Ions have a complete ?

Answer 2

Outer shell of electrons

Question 3

Ionic bonding involves

Answer 3

A transfer of electrons from metal atoms to non metal atoms

Question 4

Metal atoms lose or gain

Answer 4

Lose electrons to become POSITIVELY CHARGED IONS

Question 5

Non metal atoms gain or lose

Answer 5

Gain electrons to become NEGATIVELY CHARGED IONS

Question 6

Question 8

Ionic compounds are:

Answer 8

• giant structures of ions
• held together by strong forces of attraction that act in all directions between oppositely charged ions, HELD BY TOGETHER BY STRONG IONIC BONDS

Question 9

Ionic compounds :

Answer 9

• have high melting and boiling points
• do NOT conduct electricity when solid because the ions cannot move
• do electricity when MOLTEN or in solution because the ions can move and carry their charge
