Phophorus, whose allotropes are red phosphorus, white phosphorus , black phosphorus, violet phosphorus
blue
This may mean phosphorus which has a number of allotropes some of which are based on their colour White phosphorus - P4 red phosphorus - amorphous and three crystalline forms all polymeric in nature black phosphorus - three forms are known - again polymeric violet phosphorus (aqlso called Hittorfs phosphorus) As you can see some of the coloured forms exist in different crystalline forms and therefore colour alone is not a good indication of which allotrope is meant. The wikipedia artcle is inaccurate- if you can access Greenwood and Earnshaw "Chemistry of the e lements" that has a good write up.
An element's identity is based on the number of protons in its nucleus, which determines its atomic number. Each element has a unique number of protons, which distinguishes it from other elements on the periodic table.
Based upon is written more often.
the atomic weight scale is based upon the relative atomic masses of elements compared to carbon-12, which has an assigned value of 12. This standardization allows for consistency and accuracy in comparing the masses of different elements.
Vertical groups are families. Bonding power is based upon the type of bond, the position of element in periodic table.
This is based upon the chemical characteristics of the elements that are present within the molecular formula.
The story upon which Beowulf is based had its origins in the Norse and Anglo-Saxon traditions. It combines elements of both cultures, blending Norse mythology with Anglo-Saxon history and heroic ideals.
Based upon the light spectrum colors are different wavelengths of light. Think about it as on the same wavelength as microwave and gamma.
