They have a low density, they react with non-metals to form an ionic compound with 1+ charge, they react with water to produce hydrogen, they make solutions alkaline
1 of 10
What happens to Alkali Metals as you go down the group?
They get more reactive and their melting and boiling points get lower
2 of 10
Compared to Alkali Metals what are the Transition Metals like?
They have high melting and boiling points, they are harder and stronger and they are much less reactive
3 of 10
Name three properties of Transition Metals
They form ions with different charges, they form coloured compounds and they are useful catalysts
4 of 10
Name four properties of the Halogens
They have coloured vapours, they exist as molecules, they form ionic bonds with metals to get a 1- charge and they will displace a less reactive halogen from an aqueous solution of its salt
