29/03/2004 By: Ibrahim al Saieg Contents page 1. Introduction. 2. Apparatus list. 3. Implementation. 4. Analysing evidence and drawing conclusions. 5. Evaluating evidence and procedures. Introduction With this experiment we can determine the relative atomic mass of Lithium. I am going to calculate the relative atomic mass of lithium by using two methods. These methods will be explained further in this coursework. Lithium is an Alkali earth metal. Now I am going to introduce Lithium and the group 1 elements: The elements of Group 1, the Alkali metals, are: symbol electron configuration lithium Li [He]2s1 sodium Na [Ne]3s1 potassium K [Ar]4s1 rubidium Rb [Kr]5s1 caesium Cs [Xe]6s1 francium Fr [Rn]7s1 In each element the valence electron configuration is ns1, where n is the period number. The last element, francium, is radioactive and will not be in this coursework. Physical Properties The alkali metals differ from other metals in several ways. They are soft, with low melting and boiling temperatures. They have low densities...
