INDIAN GEOGRAPHY

Detailed explanation-1: -Graphite is a soft, crystalline polymorph of carbon, and while it shares the same chemistry as diamond the two have very different physical properties (see diamond for examples). Graphite exhibits both metallic and non-metallic properties.

Detailed explanation-2: -Chromite is an ore of chromium, bauxite is an ore of aluminium and tungston are metallic in nature while graphite is an allotrope of carbon and a carbonaceous compound. It is a very soft allotrope of carbon while other allotrope of carbon diamond is the hardest known element on this earth.

Detailed explanation-3: -Nonmetallic minerals are, for example, sand, gravel, limestone, clay, and marble. Such materials lack metallic characteristics like good electric and thermic conductivity, luster, rigor, and malleability; they are, however, essential for many industries.

Detailed explanation-4: -Graphite. Graphite is a mineral composed of stacked sheets of carbon atoms with a hexagonal crystal structure. It is the most stable form of pure carbon under standard conditions.

Detailed explanation-5: -Graphite is a soft, crystalline form of carbon. Other forms are diamond and fullerenes ("buckyballs"). It is gray to black, opaque, and has a metallic luster. It is flexible but not elastic.
