The ability to conduct electricity is one of the key properties of a metal. Other solid materials such as silicon 
can conduct electricity but only effectively at certain temperatures. Also, some substances such as salt (sodium 
chloride) can conduct when molten or when dissolved in water. The ability of metals to conduct electricity is 
due to how their atoms bond together. In order to bond together the metal atoms lose at least one of their 
outermost electrons. This leaves the metal atoms with a positive charge and they are now strictly ions. The 
lost electrons are free to move in what is known as a sea of electrons. Since the electrons are negatively 
charged they attract the ions and this is what keeps the structure together. 
An electric current is a flow of charge and since the electrons in the sea of electrons are free to move they 
can be made to flow in one direction when a source of electrical energy such as a battery is connected to the 
metal. Hence we have an electric current flowing through the wire, and this is what makes metals such good 
conductors of electricity. The only other common solid conducting material that pencil users are likely to 
encounter is graphite (what the ‘lead’ of a pencil is made from). Graphite is a form of carbon and again the 
carbon atoms bond in such a way that there is a sea of electrons that can be made to flow as an electric 
current. Likewise, if we have an ionic substance like salt we can make the electrically charged ions flow to 
create a current but only when those ions are free to move, either when the substance is a liquid or dissolved in 
water. In its solid state an ionic substance like salt cannot conduct electricity as its charged ions cannot flow. 
Electrical insulators are substances that cannot conduct electricity well either, because they contain no 
charged particles or any charged particles they might contain do not flow easily. Water itself is a poor 
conductor of electricity as it does not contain a significant amount of fully charged particles (the ends of a water 
molecule are partly charged but overall the molecule is neutral). However, most water we encounter does 
contain dissolved charged particles, so it will be more conductive than pure water. Many of the problems that 
occur when touching electrical devices with wet hands result from the ever-present salt that is left on our skin 
through perspiration and it dissolves in the water to make it more conductive.
