Explanation:

1)Allotropy or allotropism (from Ancient Greek ἄλλος (allos), meaning 'other', and τρόπος (tropos), meaning 'manner, form') is the property of some chemical elements to exist in two or more different forms, in the same physical state, known as allotropes of the elements.

2)The structure of these crystalline carbon allotropes consists of sp chains inserted in cylindrical cavities periodically arranged in hexagonal diamond (lonsdaleite). U carbon is predicted to consist of corrugated layers tiled with six- or 12-atom rings, linked by covalent bonds.

3)Graphite is mostly used for refractory, battery, steel, expanded graphite, brake linings, foundry facings, and lubricants. ...

hope it will help u ✌️
