Ionic bonding

Question 1

How do metals bond to non metals (Ionic bonding)

Answer 1

Metal atoms donate electrons to non metal ions to form ions.

Question 2

Dot and cross diagrams

Answer 2

These show the electrons on the outer shell, metals always end up with an empty outer shell while non metals will always end up with a full outer shell.

Question 3

What do the charges need to add up to in an ionic compound

Answer 3

ZERO

Question 4

Ionic compound structures(3)

Answer 4

-Ions are arranged in a Lattice of repeating units of positive and negative ions.(These form a crystal)
-High melting/boiling points due to the strong ionic bonds (strong electrostatic forces between them).
-Can conduct electricity in liquid form. This is because the ions are free to move in these states, and they carry charge

Question 5

What are Ionic compounds also called

Answer 5

Salts

Question 6

Positive ions are also known as

Answer 6

Cations ( CAT + IONS)

Question 7

Negative ions are also known as

Answer 7

Anions (AN + IONS)

Question 8

What are ions

Answer 8

-charged particles that form when an atom / molecule either gains or loses electrons
- either positive or negative

Question 9

An ionic compound ending in -ate must have how many different elements?

Answer 9

3 or more
