Most metals share a lot of properties, such as being good conductors of heat and electricity. Non-metals often have the opposite properties. For example, they are usually poor conductors of heat ...

It may be this doubly favourable combination that allows non-metallic elements to perform the reaction. Metal oxo catalysts can operate through oxyl forms, M–O ·, in which the oxygen has ...

Our bodies require other elements, including non-metal elements such as phosphorus (P), sulphur (S) and chlorine (Cl), and metal elements like potassium (K), sodium (Na), calcium (Ca) and ...
