User talk:Sandbh/Nonmetal redraft
A point about biology
[edit]I suggest a slight rewording somewhat on the following lines:
Instead of: "Living organisms are composed almost entirely of nonmetals,[3] and nonmetals form many more compounds than metals", say something like:
"Nonmetals form many more compounds than metals. Largely because of their almost uniformly high content of water (H and O), C and N, living organisms, in terms of mass, are composed mainly of elements classed as nonmetals. However, there are important exceptions; in particular, the dry-weight constitution of the bodies of organisms in many groups includes large proportions of eg Ca, Fe, K, Mg, and Na. Furthermore, they contain trace quantites of many metallic elements classed as micronutrient mineral nutrient elements." JonRichfield (talk) 11:16, 26 September 2017 (UTC)
