Metals & Non-Metals

This lesson covers:

  1. The properties of metals and non-metals
  2. The features of transition metals

gain / lose / positive / negative


When metal atoms react, they electron(s) from their outer shell. 


This creates ions with a charge.

Metals are very strong, as the ions are held together by bonds. 


They also tend to be , which means they can bend without breaking. 


Non-metals, in contrast, break easily, and so are said to be .

Many transition metals can be used as catalysts. What is the definition of a catalyst?

A metal which produces a ringing sound when struck

A substance that can speed up a chemical reaction without being used up

A compound containing both metal and non-metal elements

Diagram showing different coloured solutions of transition metal ions with charges 2+, 3+, and 6+.

Transition metals share the same properties as metals, however, they have their own section of the periodic table between groups 2 and 3. 


These metals can create ions of different charges, and form different coloured solutions.
