'A' is an element having four electrons in its outermost oebit . an allotrop 'B' of this element is used as a dry lubricant in machinary and in pencil leads.so. (a) write the name of the 'A' and its allotrope. (b) state weather the'B'is an food conductor or non conductor of electricity.

By the way, it should be 'good' instead of 'food' in ques. (b)
Hope it helps.

The element A is Carbon as it has r valence electrons. This statement is justified by the next answer. B is graphite which is an allotrope of carbon and used as a dry lubricant in machinery and in pencil leads. This justified the First statement that the element A is Carbon.
(a) The substance A is Carbon and it's allotrope is graphite.
(b)B that is graphite is a good conductor of electricity as inside each layer of graphite , free electrons move continuously within the entire layer.
