1.	The position of three elements A, B and C in the periodic Table is shown below: (a) State whether A is a metal or non-metal (b) State whether C is more reactive or less reactive than A ( c) Will C be larger or smaller in size than B? (d) Which type of ion, cation or anion, will be formed by element C?
Answer» Solution :a) A is a non METAL. b)C is less reactive than A, as reactivity decreases down thegroup M halogens. c)C will be smaller in SIZE than B as MOVING across a PERIOD, the nucleus come closer to the nucleus d) A will FORM an anion as it accepts an electron to complete itsoctet
