1. The atoms are arranged in the periodic table according to their;

• Atomic number (the number of protons)

• Properties (the way they react)2. The atoms also increase in mass,

though there is one exception (Argon and Potassium)

1. Over 75% of elements are metals. 2. Metals are good conductors of heat

and electricity. They have high melting and boiling points and are strong.

3. Less than 25% of elements are non-metals.

4. Non-metals are poor conductors of heat and electricity. They have low melting and boiling points and are brittle when solid

1. Group 1 elements are called alkali metals2. They all react quickly with water

releasing hydrogen and forming hydroxides (which are alkaline)

3. As you go down Group 1 the elements;• become more reactive (the electrons are

more easily lost)• have lower melting and boiling points

1. Transition metals are typical metals. • have high melting points• are hard, tough and strong• react slowly with oxygen and water (or

not at all)2. Iron is used for building, copper is

used for electrical cables3. Transition metals form coloured

compounds (e.g. pottery glazes)4. Some are used as catalysts
