Metallic bonding

Question 1

Metal atoms + non metal atoms =
Non metal atoms + non metal atoms =
Metal atoms + metal atoms =

Answer 1

ionic bonding
covalent bonding
metallic bonding

Question 2

What holds metal atoms together to form a piece of atom ?

Answer 2

In a metal the atoms lose several of their outer ELECTRONS. As they have lost a few electrons the atoms become positive ions. Free (delocalised) electrons drift with their own outer shell.

Question 3

What are the properties of metals ?

Answer 3

Good conductors of heat and electricity
Usually positive ions
Mast of the time - solid
They are shiny
High melting point
Malleable (hammered or pressed into shape)

Question 4

Why are metals are good conductors for heat and electricity ?

Answer 4

Because they have free and delocalised electrons.

Question 5

What are alloys ?

Answer 5

Alloys are usually harder and less malleable than pure metals.

Question 6

Does ion have an unequal positive or negative charge or equal ?

Answer 6

Unequal for ions, atoms have an equal positive or negative charge.
