Element cannot be split up into simpler substances by chemical means. Michael Bailey & Marlena . Artis. Atomic Mass. Symbol. (Uranium). Atomic Number. The atomic number is the number of protons an atom has. The atomic mass is the atom’s mass often measured in AMUs (Atomic mass units) which weighs approximately 1/12 the mass of a carbon-12 atom. Metals. By. Elizabeth Ratcliffe. Properties of Metals. Metals are useful – most are good conductors of electricity and heat. Most are shiny when they are cut. Some are magnetic such as steel. . Every metal, except mercury, is not a liquid at room temperature. . Elements in Group 1 are called . alkali metals. . lithium, sodium, potassium, rubidium, cesium, and francium . • Alkali metals are so named because they are metals that react with water to make alkaline solutions. .

All atoms want to have a completely full valence shell (normally 8 electrons).. For the moment we will only concentrate on main group elements. Noble gases are already full.. Elements that are really close, desperately want to get there (halogens and alkali), and tend to be the most reactive.. Nora . Zannoni. Valerie Gros, Roland Sarda-Esteve,.
