Fill in the chart to summarize information on important groups on the periodic table. Examples of Name of Group Elements in Description of Properties and Facts Group # this Group (use symbols) All soft silvery metals. Most reactive of all the groups of metals. Li, Na, K, Rb, alkali Has one valence electron loses to form ion in a compound. – 1 metals Cs, Fr Get more reactive as you go down the group. Francium is the most reactive in the group. All reactive with so must be stored under mineral oil. These are all silvery metals. alkaline Also reactive with water. Be, Mg, Ca, 2 earth Has two valence electrons. Sr, Ba, Ra metals They get more reactive as you go down the group. The most reactive in this group is Radium. All non-metals. Found in all three states: F & Cl are gases, Br is a liquid and I and As are solids. F, Cl, Br, 17 halogens Has seven valence electrons gains an electron to form – I, At stable ion in a compound. Get more reactive as you go up the group. Fluorine is the most reactive. All non-metals and gases. He, Ne, Ar, Have full outer orbitals unreactive 18 noble gases Kr, Xe, Rn They are non-reactive elements and therefore do not form compounds These are all metals and solid except for mercury which is a liquid. Zn, Au, Pb, transition 3-12 They have typical metallic properties and many of them metals Hg, Ni, Cu are the most commonly known metals e.g. iron, copper, tin, lead, silver, gold etc.
