Metals and reactivity, electron arrangements, uses and properties of metals notes

Gold is an unreactive metal, it is found in the Earth as a metal.

Aluminium is an element because Aluminium is made of only one type of atom.

The Nucleus of an atom contains protons protons and neutrons.

In the periodic table, Aluminium in in Group 3.

The correct chemical symbol for Aluminium is Al.

Aluminium should be recycled because it is a limited resource and it is can be expensive to extract.

Aluminium has a low density, conducts electricity and is resisitant to corrosion. As it will not corrode easily and destroys what is inside it to make it fresh.These particles can help stop it breaking down.

Transition metals, Properties of metals, quarrying and the environmental impact, mass calculations 

Copper is a transition metal. It is found in the central block in the periodic table.

A property of Copper is that it conducts electricity.

Copper ores are quarried by digging large holes in the ground.

Quarrying is bad for the environment because it can destroy habitats in the environment. Quarrying also creates lots of noise and dust pollution.

Some copper ores contain only 2% copper. Most of the ore is rock that is not needed. In one ore, the main compound is copper carbonate(CuCO3).

The stages used to extract copper is shown below

Stage 1: Crush the copper ore so it is now a powdered ore.

Stage 2: Separate the rock from the carbon carbonate.

Stage 3: Extract the copper metal from the copper metal using carbon. You are then left with Copper metal and Carbon Dioxide.

Stage 2 is importnt because it helps to separate the rock and copper carbonate inside of it.

Crude oil, fractional distillation, word equations, impact of sulfur dioxide, alkenes and alkanes

Crude oil is a fossil fuel.

To make crude oil more useful it is separated into fractions. 

Crude oil is a mixture of sifferent substances.

The substances in crude oil have different boiling points.

Crude oil is separated by fractional distillation.

Petrol is one of the fractions produced from crude oil.

Car engines use a mixture of petrol and…
