WebThe three crowns represent the three major forms of the element in nature and carbon’s status as ‘King of the Elements’ in the periodic table. Appearance There are a number of pure forms of this element including graphite, diamond, fullerenes and graphene. Diamond is a colourless, transparent, crystalline solid and the hardest known material. Many terms have been used in the literature to describe sets of elements that behave similarly. The group names alkali metal, alkaline earth metal, triel, tetrel, pnictogen, chalcogen, halogen, and noble gas are acknowledged by IUPAC; the other groups can be referred to by their number, or by their first element (e.g., group 6 is the chromium group). Some divide the p-block elements from group…
