Can u give some allotropes of element ???? Please name them.?

Question

Please give names of elements and theie allotropes.

Note: give other than that of carbon.

Answer 1

Sulphur has several allotropes, the most common being S8; Boron has several as well, the easyest to prepare being B12. Phosphorous is a typical example, the white, which has the formulae P4, and the polymeric red and black, the least reactive of all. The allotrope of oxygen is ozone, O3. You can go on, finding some more. Apparently, an allotrope of nitrogen is N5; tin has two allotropes, one of which is the one called grey tin. If you search for the families of the right of the Table, you may find even more elements which form allotropes which I do not remember right now. But the ones I gave you might serve.

Answer 2

Which Elements Have Allotropes

Answer 3

Allotropes are different forms of the same element. Different bonding arrangements between atoms result in different structures with different chemical and physical properties. Allotropes occur only with certain elements, in Groups.

Answer 4

Allotropes are rare, free oxygen and ozone are two examples.

An allotrope is when an element takes on a different chemical structure in different situations. For example carbon can be independent as graphite, a carbon ring as benzine, a diamond, a buckyball, or a carbon nanotube. It has the most allotropes of any element.

According to Wikipedia: http://en.wikipedia.org/wiki/Allotropes
"Allotropy (Gr. allos, other, and tropos, manner) is a behavior exhibited by certain chemical elements: these elements can exist in two or more different forms, known as allotropes of that element. In each different allotrope, the element's atoms are bonded together in a different manner.

For example, the element carbon has two common allotropes: diamond, where the carbon atoms are bonded together in a tetrahedral lattice arrangement, and graphite, where the carbon atoms are bonded together in sheets of a hexagonal lattice.

Note that allotropy refers only to different forms of an element within the same phase or state of matter (i.e. different solid, liquid or gas forms) - the changes of state between solid, liquid and gas in themselves are not considered allotropy. For some elements, allotropes have different molecular formulae which can persist in different phases - for example, the two allotropes of oxygen (dioxygen, O2 and ozone, O3), can both exist in the solid, liquid and gaseous states. Conversely, some elements do not maintain distinct allotropes in different phases: for example phosphorus has numerous solid allotropes, which all revert to the same P4 form when melted to the liquid state.

Examples:

Phosphorus:
Red phosphorus - polymeric solid
White phosphorus - crystalline solid
Black phosphorus - semiconductor, analogous to graphite

Oxygen:
dioxygen, O2 - colorless
ozone, O3 - blue
tetraoxygen, O4 - red

Sulfur:
Plastic (amorphous) sulfur - polymeric solid
Rhombic sulfur - large crystals composed of S8 molecules
Monoclinic sulfur - fine needle-like crystals
Molecular sulfur - sulphur tends to form ring molecules such as S7 and S12

Plutonium has six distinct solid allotropes under "normal" pressures. Their densities vary within a ratio of some 4:3, which vastly complicates all kinds of work with the metal (particularly casting, machining, and storage). A seventh Plutonium allotrope exists at very high pressures, which adds further difficulties in exotic applications."
