Diamond, graphite, limestone, chalk, oil and natural gas
3 of 26
Where is hydrogen mostly found?
Most hydrogen atoms are joined to oxygen atoms in the compound water
4 of 26
Why is hydrogen used as fuel?
Because it is a gas at room temperature

Where is oxygen mostly found?
Oxygen is all around us in the air
6 of 26
What are things reacting with when they burn?
Oxygen

If it is bubbled through limewater, the clear limewater will become cloudy
11 of 26
What is the test for hydrogen gas?
Hydrogen makes a lit splint make a popping sound
12 of 26
What is the test for oxygen gas?
Oxygen relights a glowing splint

Silicon and other semi-metals are on the borderline of metals and non-metals
21 of 26
What is silicon used for?
Gemstones are made of silicon dioxide. Most of the world's rocks are made of silicon dioxide. Silicon makes microchips for electrical devices
22 of 26
What do the uses of elements depend on?
Their properties
23 of 26
Are the properties of compounds the same or different to those of the elements in them?
Different
