What is the natural abundance of pnicogens (poison metals in the periodic table, group/family 15)?
March 12th, 2010 | by admin |What is the natural abundance of the following elements in their natural state?
Nitrogen
Phosphorous
Arsenic
Antimony
Bismuth
Also, what is the trend of reactivity (if possible, you don’t have to answer this)
N: 99.69999% as 14N, 0.366% as 15N
P: 100% as 31P
As: 100% as 75As
Sb: 57.36% as 121Sb, 42.64% as 123Sb
Bi: 100% as 209Bi
Based on periodic trends, the reactivity of N should be highest and that of Bi the lowest (based on ionization energy and electronegativity). All the pnicogens bond quite tightly to other elements (they make good double and triple covalent bonds).
