Question

Elements forming ionic compounds attain noble gas electronic configuration by either gaining or losing electrons from their valence shells. Explain giving reason why carbon cannot attain such a configuration in this manner to form its compounds. Name the type of bonds formed in ionic compounds and in the compounds formed by carbon. Also explain the reason why carbon compounds are generally poor conductors of electricity.OR(1)‘‘A’ is an element having four electrons in its outermost orbit. An allotropeB’ of this element is used as a dry lubricant in machinery and in pencil leads. So(i) Write the name of element ‘A’ and its allotropes.(ii)State whether ‘B’ is a good conductor or non-conductor of electricity.(2)‘E’ is an element which reacts with oxygen to form an oxide E₂O. An aqueous solution of E₂O turns red litmus blue, so(1)What is the nature of oxide E₂O?(2)Write the name of element ‘E’.
