Covalent bonding is the sharing of pairs of electrons between two non-metallic atoms.

Ionic bonding is where electrons are transferred from one atom to another, usually from a metallic at...

For a reaction to be spontaneous delta G has to be negative according to the equation delta G = delta H - TdeltaS. Therefore if the temperature of a reaction is very high then -TdeltaS will be greater ...

Poly(ethene) is formed when several monomers of ethene (an alkene) are joined together. Ethene can take part in this type of reaction as it is has a double bond (it's unsaturated) which opens up to all...

The easiest way to think about this is as the 'law of opposites' TemperatureExothermim reactions: If temp is increased then the reaction moves in the direction to reduce this rise of temp by shifti...

As you progress down the group:- Atomic radius increases, therefore there is more electron shielding.- There is an increase in the nuclear charge, however it is outweighed by the increase in shielding.- I...
