Allotropes
have the same atomic number, number of protons, number of
electrons, etc. but the chemical and physical properties may differ strongly.
allotrope
Each of two or more different physical forms in which an element can exist.
O3 is the allotrope of oxygen that is isoelectronic.
Sulphur and helium have entirely different properties. Sulphur has properties similar to group 16 elements. Helium has properties similar to group 18 elements.
Elements have more similar properties when they are found in the same column. Elements in the same column, also known as group or family, have similar chemical properties because they have the same number of valence electrons. Elements in the same row, also known as period, have different properties because they have different electron configurations.
No silicon is an element in the same group as carbon, it has similar chemical properties but it is not carbon.
allotrope allotrope =)
The element whose allotrope is ozone is oxygen. It is one of the main part of ecosystem.
From Wikipedia: "Allotropy or allotropism is a behavior exhibited by some chemical elements: these elements can exist in two or more different forms, known as allotropes of that element. In each allotrope, the element's atoms are bonded together in a different manner." Conversion, therefore (logically) would mean that one would be able to reduce the carbon allotrope to atoms and then re-assemble them into a different allotrope. For example, in order to form a diamond allotrope from a group of carbon atoms requires enormous amounts of pressure and temperature.
allotrope of carbon i.e. graphite
allotrope
AllotropismThe form of an element having a different molecular structure is a Allotrope. Examples of an Allotrope are diamonds and graphite. An Allotrope is a carbon.

O3 is the allotrope of oxygen that is isoelectronic.
Allotrope
In that case, scientists talk about different "allotropes". For example, graphite and diamond are different varieties of carbon - the same atoms, in a different arrangement.
