alkali metals

A
periods
7

similar
8

10
Q
metal properties
A
- metals conduct electricity because they allow charge to pass through them easily
- metal oxides are basic - this means they will neutralise acids
- metal oxides which dissolve will form solutions with a pH of more than 7
11
Q
non-metal properties
A
- non-metals are poor conductors of electricity
- non-metal oxides are acidic - this means that they will neutralise bases
- they dissolve in water to form solutions with a pH of less than 7
12
Q
group 0 element properties
A
- group 0 elements are noble gases
- they are inert (unreactive) and colourless gases
- the reason for this is that it takes a lot of energy to add or remove electrons from a noble gas atom
