CELLS All living things are made of cells‚ and cells are the smallest units that can be alive. Life on Earth is classified into five kingdoms‚ and they each have their own characteristic kind of cell. However the biggest division is between the cells of the prokaryote kingdom (the bacteria) and those of the other four kingdoms (animals‚ plants‚ fungi and protoctista)‚ which are all eukaryotic cells. Prokaryotic cells are smaller and simpler than eukaryotic cells‚ and do not have a nucleus. Prokaryote

of an atom with neutrons that carry no charge. Electrons are negatively charged and are constantly moving around the nucleus. Ions are created when electrons move from one atom to another atom changing the charge of that atom to either positive or negative. When electrons move they form bonds. There are two types of bonds; ionic and covalent. Ionic bonds are formed through electrical forces while covalent bonds are a lot stronger and are formed when atoms are forced to share electrons.
