S-Cool Revision Summary

Metals are:

  1. Strong.

  2. Malleable.

  3. Ductile.

  4. Sonorous.

Metals have high melting and boiling points.

Metals are good conductors of heat and electricity.

Non-metals are:

  1. Brittle.

  2. Dull.

  3. Not strong.

Non-metals are poor conductors of heat and electricity.

Non-metals have low melting and boiling points.

Some metals react oxygen to form oxides.

Some metals react with water to form salts. Potassium, sodium and calcium
form hydroxides, for example, alkaline solutions. Magnesium and other less
reactive metals form oxides.

Although many metals react with oxygen, water or even dilute acids, they
react differently
. Some metals are more reactive than others.

The Reactivity Series is a
list of metals in order of reactivity.

A metal will always displace a less reactive metal from solutions of its
compound - displacement reactions
.
This is because the more reactive the metal, the more easily it gives up electrons.
