1.	Name the four blocks of elements in the periodic table and list the difference in their electronic configurations. Give examples of each type of elements. Write at least four characteristics of each block.
Answer» r blocks of elements in the periodic table are as follows,s BLOCK elements Electronic configuration: where n=2- 7General characteristics:Melting point and boiling point are low and are soft metals.High electropositive and low ionisation enthalpies.Strong reducing agents.Good conductor of “electricity and heat”.p block elements Electronic configuration: General characteristics:TOP to bottom, metallic character increases within a group.Left to RIGHT, increase in “non-metallic character” along the period and form covalent COMPOUNDS.Ionisation enthalpies are higher than the s block elements. d block elements The configuration of d-block elements is (outer shell) where n=4 to 7General characteristics:Good conductor of electricity and heat.Ionisation enthalpy LIES between s and p block.Ionic and also covalent compounds formed.Oxidation states are variable.f block elements Electronic configuration: General characteristics:Heavy metals.High melting point and boiling point.Oxidation states are variable.Coloured compounds.
