The alkali metals are located in Group 1 of the periodic table. They are a series of chemical elements which have similar trends and properties. Alkali metals are so called because when they react with water alkalis (strong bases that can neutralize acids) are formed.. Properties of Metals. Worksheet .  Metals. ¾ of all known elements. Solid at room temp (NOT Mercury). Low IE = give up electrons. Metallic bonds. Delocalization. Malleable, ductile. Alkali Metals. 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.. All atoms want to have a completely full valence shell (normally 8 electrons)..

Densities Reactivity… Alkali Metal What is the trend in density? The alkali metals generally become more dense going down the group, but the trend is not perfect because potassium is less dense than sodium. Periodic Table. B. 2p. 1. H. 1s. 1. Li. 2s. 1. Na. 3s. 1.
