Caesium is the most reactive metal in the periodic table, so much that working with this metal often ends in explosions! These are (except for hydrogen) soft, shiny, low-melting, highly reactive metals, which tarnish when exposed to air. The measure of an elements ability to pull electrons towards it is known as electronegativity. This means that the atoms of non-metals have a strong tendency to hold on to the electrons that already have. Hydrogen, chlorine, fluorine, carbon, nitrogen, phosphorus, selenium are examples of non-metal. Group 18 elements are nonmetals called noble gases (see Figure below).
