Electricity is the movement of charge and therefore something charged must move to carry this charge. graphite carbon atoms make 3 covalent bonds with the adjacent atoms however carbon has 4 electrons in its...

The equipment needed is a bunsen burner, a wire loop, some HCl, and the compound being tested (usually in powder form). Set up the bunsen burner so that it is on a blue flame. Take the wire loop and dip it i...

Isotopes are atoms of the same element that have the same proton number but different nucleon number. TRAIN OF THOUGHT --- Isotopes have the same proton number --- uncharged (neutral/unionised) molecules hav...

A chemical reaction occurs when bonds are broken and formed between atoms. Energy is taken in in order to break bonds; when a bond is formed the molecule becomes more stable, so energy is given out. The enth...

When elements are heated, it causes their electrons to become excited. Electrons exist in discrete energy levels, and these energy levels are unique to each element. When the electrons are excited by heat, t...
