The atom is the basic unit of all matter on Earth and in the Universe. Although the Periodic Table contains most of the discovered atoms on Earth, there are still many more unknown atoms that may be present within space and beyond.
Made from elementary particles and held together by fundamental forces, they drive the chemistry of the universe. Each one has a tiny, positively charged nucleus, balanced by a cloud of negatively charged electrons. These determine the atom’s properties. Split an atomic nucleus open and you’ll...
