1 Allotropes are forms of the same element which exhibit different physical properties. 2  Elements such as carbon, oxygen, phosphorus, tin and sulfur, display allotropy.llotropes of Carbon. Both graphite and diamond are made up of carbon atoms, but the arrangement of atoms is different in each allotrope which results in different physical properties.
There are several known allotropes of oxygen. The most familiar is molecular oxygen (O 2), present at significant levels in Earth's atmosphere and also known as dioxygen or triplet oxygen.Another is the highly reactive ozone (O 3). Others include: 1  Atomic oxygen (O 1, a free radical).2  Singlet oxygen (O 2 *), either of two metastable states of molecular oxygen.ee also: Dioxygen in biological reactions. The common allotrope of elemental oxygen on Earth, O 2, is generally known as oxygen, but may be called dioxygen or molecular oxygen to distinguish it from the element itself.
