Chemistry and electricity are linked.
Atoms are made of nucleus and negative charged electrons.
An atom is normally electrically neutral.Atoms can lose or gain electrons to form charged ions. Discharge of ions involves loss or gain of electrons.
There are two types electric charge:positive and negative.The flow of electric charge in a conductor is an electric current.There will only be an electric current in a conductor when there is a potential difference across the conductor.It is measured in volts.
Chemical reactions may be used to produce potential differences-
electric current .These reactions are the basis of voltaic cells.Elecricity is involved in the production of some chemicals by electrolysis.
