Topic 3 - 3.1 - Ionic Bonding

Question 1

All —— lose —– to become positive ions and all ____ gain electrons to become ____ ions.

Answer 1

All metals lose electrons to become positive ions and all non-metals gain electrons to become negative ions

Question 2

Do ionic bonds have high melting/boiling points or low melting/boiling points? Explain your answer

Answer 2

They have high melting/boiling points because they are really strong.

Question 3

What is an IONIC BOND?

Answer 3

It is an electrostatic force of attraction between positivley charged ions and negativley charged ions. It occurs between a metal and non-metal.

Question 4

Do most ions have colour?

Answer 4

No, they are colourless. When they are in a solid compound, they appear white.

Question 5

When do ionic substances conduct electricity? Explain why this is.

Answer 5

They only conduct electricity in solution or molten (liquid) .This is because the ions are able to move freely in solution or liquid form.

Question 6

Define Valency

Answer 6

Number of electrons needed to lose or gain to become stable
