Paragraph Questions 5. Why are first row transition elements more commonly found in biological systems, rather than second or third row elements? (4 points) What factors does nature consider when selecting elements for particular roles, give three? (6 points) 6.
Solution
Ans 5 :
Usually the first row transition elements such as iron , manganese , copper , cobalt , zinc etc are present in the biological systems as they play a major role in the biological processes of the body.
The second and third row elements are inert and hence they do not engage themselves in the metabolic processes of the body. So these elements are not formed in biological systems except Molybdenum.
