Conduction is possible as delocalised (free) electrons are able to carry a charge and move through the metal.

Ionic bonds exist between metals and non metals for example sodium and chlorine. Metals have one to three electrons in their outer shell which can be transferred to a non metal. This means that the metal ...

Covalent bonding relies on the fact that all atoms are desperately trying to get a full outer shell of electrons. By full outer shell we mean 2 electrons in the first shell, 8 in the 2nd shell, 8 in th...

Each row on the periodic table represents a new energy level/electron shell. So as you go down the group there are more energy levels, increasing the atomic radius. The first electron to react will be ...

So, there are two parts to this question. 

Firstly, you need to decode the words in the question and transform this into an equation. 

From chemical knowledge, you know: aci...
