Some elements are found in nature in more than one form. They have same chemical properties but diffrent physical properties. They are called allotropes.

Yes, due to the different arrangement of carbon atoms.

Yes, in diamond structure one carbon atom bonded with other four different carbon atoms and form tetrahedron shape. Graphite has a layered, planar structure In each layer, the carbon atoms are arranged in a hexagonal lattice.

Allotropes have same chemical properties butt different physical properties.

Allotropes:.

Allotropy or allotropism is the property of some chemical elements to exist in two or more different forms, known as allotropes of these elements. Allotropes are different structural modifications of an element but having the same chemical composition for e. G Diamond, graphite have the same chemical composition but they have different structures. It is for this reason that diamond is the hardest known element whereas graphite is extremely soft.

Isomers:.

Are compounds with the same molecular formula but different structural formulas.

Isomorphs:.

An isomorph is an organism that does not change in shape during growth. The implication is that its volume is proportional to its cubed length, and its surface area to its squared length. This holds for any shape it might have; the actual shape determines the proportionality constants.

Isotopes:.

Isotopes are variants of a particular chemical element. While all isotopes of a given element share the same number of protons, each isotope differs from the others in its number of neutrons.

For example, carbon-12, carbon-13 and carbon-14 are three isotopes of the element carbon with mass numbers 12, 13 and 14 respectively.

ALLOTROPY IS THE EXISTING OF ELEMENTS IN THE SAME PHYSICAL. CARBONS, DIAMONDS, GRAPHITES, COAL HAVE THE SAME PHYSICAL STATE. For example, diamonds and coal are allotropes of the element carbon.

Carbon, graphite and diamond, collectively cannot be called allotropes because here carbon is the parent element and graphite and diamond are its allotropes, so we cannot place them altogether,

I would like to suggest a correction in question itself i.e. there should be "amorphous carbon" in place of carbon as it is an allotrope of carbon.

Friends,

Can anybody give the structure of diamond and graphite?

What the answer to this?

An element always has the same set of properties.

Answer is allotrope and Eight allotropes of carbon: a) diamond, b) graphite, c) lonsdaleite, d) C60 buckminsterfullerene, e) C540, Fullerite f) C70, g) amorphous carbon, and h) single-walled carbon nanotube.
