 * ======Serial No====== || ====== **Assessment Statement.**  ======

//All candidates should be able to://
|| ======Covered in Class====== || ======Revised @ home====== || ======I am certain====== || ======I need help====== ||
 * ====== 1  ====== || ======Describe the way the Periodic Table classifies elements in order of proton number.====== ||   ||   ||   ||   ||
 * ====== 2  ====== || ======Use the Periodic Table to predict properties of elements by means of groups and periods.====== ||   ||   ||   ||   ||
 * ======**9.1 Periodic trends**====== ||
 * ====== 1  ====== || ======Describe the change from metallic to nonmetallic character across a period.====== ||   ||   ||   ||   ||
 * ====== 2  ====== || ======Describe the relationship between Group number, number of outer-shell (valency) electrons and metallic/non-metallic character.====== ||   ||   ||   ||   ||
 * ======**9.2 Group properties**====== ||
 * ====== 1  ====== || ======Describe lithium, sodium and potassium in Group I as a collection of relatively soft metals showing a trend in melting point and reaction with water.====== ||   ||   ||   ||   ||
 * ====== 2  ====== || ======Predict the properties of other elements in Group I, given data where appropriate.====== ||   ||   ||   ||   ||
 * ====== 3  ====== || ======Describe the trends in properties of chlorine, bromine and iodine in Group VII including colour, physical state and reactions with other halide ions.====== ||   ||   ||   ||   ||
 * 4 || Predict the properties of other elements in Group VII, given data where appropriate. ||  ||   ||   ||   ||
 * 9.3 Transition elements ||
 * 1 || Describe the transition elements as a collection of metals having high densities, high melting points and forming coloured compounds, and which, as elements and compounds, often act as catalysts. ||   ||   ||   ||   ||
 * **9.4 Noble gases** ||
 * 1 || Describe the noble gases as being unreactive. ||   ||   ||   ||   || ﻿ ||
 * 2 || Describe the uses of the noble gases in providing an inert atmosphere, i.e. argon in lamps, helium for filling balloons. ||   ||   ||   ||   ||
