metallic bonding

Metals consist of

Giant structures of atoms arranged in a regular pattern

Electrons in outer shells of atoms in metallic bonding are

Delocalised

Delocalised

Free to move

The sharing of delocalised electrons results In

Strong metallic bonding

Properties of metals

• Electrical conducters

• Good conducters of thermal energy because delocalised electrons can carry energy

• High melting and boiling points due to strong bonds

An alloy is a

Mixture of two or more elements where at least one of them is a metal

Why do we create alloys

Because many metals are too soft for their uses

How does making a pure metal int an alloy make the substance stronger?

The alloy has different sized atoms, which disrupts the structure and makes it so the layers of the metal can no longer slide over ea hother

The stronger the metal, the

Greater the force needed to make the layers slide over each other
