Step-by-step solution
(a) Graphite (iv) Soft and slippery material: Graphite is composed of layers of carbon atoms arranged in a hexagonal lattice. These layers are weakly bonded together, allowing them to slide over each other easily. This gives graphite its characteristic soft and slippery feel, making it suitable as a lubricant and in pencils. (b) Diamond (ii) Hardest natural substance: Diamond is made up of carbon atoms arranged in a tetrahedral lattice structure, forming a very strong covalent bond network. This structure gives dia
