To answer the question what is electricity, we must first start by talking about an atom. An atom is made up of protons, neutrons and electrons. Protons (positive charge) and neutrons (neutral charge) form the nucleus, while electrons (negative charge) orbit the nucleus. The atom is considered balanced if the protons and electrons are equal. But if the atom loses or gains an electron it becomes an unbalanced atom. The loss of electrons causes the atom to have a positive charge because there are more positively charged protons than electrons. The gain of electrons causes the atom to have a negative charge because there are more negatively charged electrons than protons. Since there is a missing electron, either the lost electron searches for another atom with a missing electron to join or the atom with the missing atom will search for a lone electron to pair to join it. The transfer of electrons is what causes electricity. When electrons move from one atom to another they create an electric flow or current. Scientists are able to purposely cause atoms to lose electrons, so that they produce electricity. (www.energyquest.ca.gov) There are many different sources for creating electricity. Some are better than others for various reasons, but all the main ways to produce electricity are nuclear fission, nuclear fusion, solar panels, oil, coal, windmills, tidal power, biomass, natural gas, geothermal energy, human/animal energy, hydroelectric energy. , magnetic and fuel cell. Nuclear fission involves taking an atom of uranium and splitting the nucleus in half, thus creating a lot of energy.
