Common hydrogen and at very high pressure hydrogen turns metallic (beta-hydrogen)
Diamond is the allotrope -- of carbon.
No. Ammonia is a compound. An allotrope is a substance in its elemental form.
Oxygen, Nitrogen, and Sulfur. (Though in the latter case, S2 is not the most common allotrope of Sulfur, the allotrope DOES exist.)
Yes
Because they have different properties.
Ozone is not an allotrope. It is a compound of oxygen.
Diamond is an allotrope of carbon.
Diamond is the allotrope -- of carbon.
O3 is the allotrope of oxygen that is isoelectronic.
Coal is an allotrope of carbon. When burnt, coal will give carbon dioxide. Water is not formed, because there is no hydrogen in coal that will be oxidised to water.
No. Ammonia is a compound. An allotrope is a substance in its elemental form.
Ozone is an allotrope of oxygen. It is represented as O3.
Oxygen has ozone as allotrope. It is the triatomic form of oxygen.
A diamond is an allotrope of carbon
The common allotrope of sulfur is S8.
graphite is the lowest energy of carbon allotrope
Yes, ozone is an allotrope. It is the triatomic form of oxygen.
