Groups in the Periodic table - C2 topic 4

HideShow resource information
Metals
Form Giant Crystalline Structures. Atoms packed so tightly together that their electrons become separated from them - results in a lattice structure of positive ions in a sea of free moving electrons. Good conductors of heat and electricity.
1 of 5
Transition metals - in the central block
Same properties as all metals - Malleable, ductile, dense, high melting point and good conductors of halt and electricity. as well as this, they are often brightly coloured
2 of 5
The Alkali Metals - Group 1
Soft + low melting points. Reactions with water become increasingl exothermic as they go down. Very reactive so stored under oil. Get more reactive as they go down. React with water to form hydroxides and hydrogen gas.
3 of 5
The Halogens - Group 7
5 non-metals - need to know Flourine, Chlorine, Bromine and Iodine. All exist as homonuclear diatomic molecules. Become less rective as they go down. Need to know displacement reactions of the Halogens with solutions of other halides
4 of 5
Noble Gases - Group 0
No smell. Colourless. Inert.
