Hydrogen; H 1
Non-metal. Explosive gas. Colourless and odourless. Hydrogen is the lightest of the gases, lighter than air, produced when an active metal is placed in acid.
Helium; He 2
Non-metal. Inert (unreactive) colourless gas. Lighter than air and is often used in party balloons.
Lithium; Li 2, 1
Metal. Very reactive with air and water. Used in some types rechargable batteries and in the treatment of certain mental illnesses.
Beryllium; Be 2, 2
Metal. Sometimes used in the construction of nuclear weapons.
Boron; B 2, 3
Non-metal. Found in Sodium Tetraborate (Borax) used to make Mystery Putty)
Carbon; C 2, 4
Non-metal. Found in many forms; diamond, coal, graphite. Essential to living things as it makes up the "skeleton" of many essential molecules in cells.
Nitrogen; N 2, 5
Non-metal. Colourless gas that makes up most of the atmosphere. Unreactive when breathed in. Essential to living things (found in amino acicds, protein, DNA)
Oxygen; O 2, 6
Non-metal. Colourless odourless gas required by many living things to carry out respiration. Slightly soluble in water. Essential for combustion (burning) to occur.
Fluorine; F 2, 7
Non-metal. Gas. Highly reactive with Group 1 elements
Neon; Ne 2,8
Non-metal. Inert (unreactive) gas sometimes used in shop signs (Neon lights)
Sodium; Na 2, 8, 1
Metal. Very soft., can be cut by a knife. Very reactive with air and water. Combines explosively with poisonous Chlorine gas to form Sodium Chloride - table salt.
Magnesium; Mg 2, 8, 2
Metal. Light and easily bent. Burns readily in air with a brilliant white light. Used in flares and fireworks. Found in chlorophyll in aiding the process of photosynthesis.
Aluminium; Al 2, 8, 3
Metal. Very light and quickly forms a protective oxide layer that prevents further corrosion (rusting). Used in step ladders, window frames because it does not require painting.
Silicon; Si 2, 8, 4
Non-metal. Conducts electricity and is used in computer chips. Silicon Dioxide is used as window glass.
Phosphorous; P 2, 8, 5
Non-metal. Able to glow in the dark. A major component of bones. Important element added to soil as plant fertilliser in the form of phosphate.
Sulphur; S 2, 8, 6
Non-metal. Yellow solid that smells of rotten eggs.
Chlorine; Cl 2, 8, 7
Non-metal. Green poisonous gas. Reacts explosively with Sodium metal to form salt.
Argon; Ar 2, 8, 8
Non-metal. Inert (unreactive) colourless gas. Sometimes used in welding.
Potassium; K 2, 8, 8, 1
Metal. Very soft, can be, cut with a knife. Reacts readily with water.
Calcium; Ca 2, 8, 8, 2
Metal. Major component of bones and teeth.
