—> are  non-metals                                    —> Have low boiling points 

larger because the inter molecular forces become stronger and therefore more energy is required to overcome the forces 

As you go down the group the atoms become 

As group 0 elements reactive or unreactive?

—> soft (can be cut with a knife)            —> fairly low melting points                  —> Low density 

The reactivity of alkali metals increases as

When atoms in group 0 lose one electron they form 

A hydrogen and metal oxide e.g sodium reacts with water to form sodium hydroxide and hydrogen 

Alkali metals react with water to produce 

metal oxides - at room temperatures oxygen reacts with the surface of the metal,forming a white oxide,which covers the surface.However the metal below the surface doesn’t react 

The alkali metal also react with oxygen in the air to form 

Displace a less reactive halogen from solutions of its salts 

—> tightly packaged, usually in a regular pattern                                      —> Will vibrate but can’t move past each other                                              —> Solids retain their shape 

—> Close together - no regular pattern                                                    —> Flow and can easily move or slide past                                               —> Assume shape of container 

—> Well separated with no regular pattern                                                   —> Particles in a gas vibrate freely at high speeds                                      —> Gases assume the shape of the container they are in

Mass of products = mass of reactants (unless gas has been produced and released into air)

Number of moles = mass (g) / Relative atomic mass (Ar)

Long chains that formed by joining together lots of molecules 

And therefore many intermolecular forces 

Four covalent bonds to four other carbon atoms 

Diamond melting and boiling points are very

The carbon atoms in graphite form hexagonal rings, which are arranged in layers and therefore can easily slide over eachother
