State the two properties of carbon which make it unique among other elements. State the two uses of carbon which are based on its unique property.
(A) Two properties of carbon that make it unique among other elements are:
$(i)$ Catenation: Carbon has the unique ability to form strong covalent bonds with other carbon atoms,resulting in the formation of long chains,branched chains,or ring structures.
$(ii)$ Tetravalency: Carbon has a valency of $4$,allowing it to form stable bonds with four other atoms of carbon or other monovalent elements like hydrogen,oxygen,nitrogen,or halogens.
Two uses of carbon based on its properties are:
$(i)$ Graphite (an allotrope of carbon) is used in pencil leads and as a dry lubricant due to its layered structure and weak inter-layer forces.
$(ii)$ Diamond (an allotrope of carbon) is used in cutting and drilling tools because of its extremely hard,three-dimensional tetrahedral crystal lattice structure.
