• Cations

Question 6

Group 6

Answer 6

2-

• Anion

Question 7

Group 7

Answer 7

1-

Anions

Question 8

Ionic bonding

Answer 8

Positive ions attract negative ions because opposite forces attract.
• Electrostatic forces of attraction

Question 9

What is an ion?

Answer 9

An atom or group of atoms with a charge

Question 10

Structure of an ionic solid

Answer 10

Regular lattice of oppositely charged ions

Question 11

How are metal ions formed?

Answer 11

Metals give away electrons to form + ions

Question 12

How are non-metal ions formed?

Answer 12

Non-metals gain electrons to form - ions

Question 13

Why don’t ionic substances conduct electricity as solids?

Answer 13

The ions can’t move and so can’t carry a charge

Question 14

Why do ionic substances have high melting and boiling points?

Answer 14

Strong electrostatic attraction between ions
