1.	a) Name the elements with highest and lowest electronegativity,(b) State the character of the oxide of period 3.
Answer» (a) The element fluorine has the highest electronegativity and Caesium has the lowest electronegativity. (b) The nature of oxides changes from basic to acidic as we move from left to right in third period. Hence sodium forms most basic oxide while oxide of Aluminum is amphoteric and oxides of phosphorus, sulphur and chlorine are progressively acidic
