ABSTRACT
What is electricity? To understand electricity properly we must start by finding out what it really is. This means we must think very small! The molecule is the smallest part of matter that can be recognised as that particular matter. Subdivision of the molecule results in atoms. The atom is the smallest part of matter and consists of a central nucleus made up of protons and neutrons. Around this nucleus, electrons orbit, like planets around the sun. The neutron is a very small part of the nucleus. It has an equal positive and negative charge. It is therefore neutral and has no polarity. The proton is another small part of the nucleus; it is positively charged. As the neutron is neutral and the proton is positively charged, this means the nucleus of the atom is positively charged.
