Sp3 Hybridisation

Sp2 Hybridisation
Build a molecule of methane = CH4

tell me:

1. The bond angles

3. The type of orbital overlap that each bond has
Alloys are a mixture of metals with metals or metals with non-metals. They are made for a number of reasons:
e.g Copper makes metals STRONGER
Brass - used in electrical fittings - is 70 per cent copper and 30 per cent zinc
18-carat gold - used in jewellery - is 75 per cent gold and 25 per cent copper and other metals
Duralumin - used in aircraft manufacture - is 96 per cent aluminium and 4 per cent copper and other metals ,
So alloys make metals...
1. Stronger
2. Corrosion resistant
3. Shinier
4. Change colour
5. Cheaper
