An ionic bond is the transfer of electrons from one atom to another to obtain a stable outer shell. This only happens between a metal and a non metal. For example, magnesium would transfer 2 electrons to ...

First write out the equation given:Na + O₂ —> Na₂ONow count how many oxygen atoms are on the LHS of equation (2) and how many are on the RHS (1). This means you must put a 2 in f...

Metals form metallic bonds, where unlike in covalent or ionic bonding, electrons are delocalised. This means the electrons can move freely throughout the metallic structure. Electricity is the flow of ele...

Substances can conduct electricity if there is a way for charge to flow through that substance. For a substance to conduct electricity, it needs to contain some sort of charge carrier - this could be an e...
