A unique blend of chemical and biological data. Rather than dividing elements up into the usual metal, nonmetal, and transition element groupings, this colorful table identifies each element in biological terms as basic nutrients, macronutrients, micronutrients, trace nutrients, inert elements, biotoxins, and radioactive elements.
