Bentonite - Wikipedia

Bentonite (volcanic ash) from Wyoming Gray shale and bentonites (Benton Shale; Colorado Springs, Colorado) Bentonite (/ˈbɛntənaɪt/)[1] is an absorbent swelling clay consisting mostly of montmorillonite. It usually forms from weathering of volcanic ash in seawater,[2][3] which converts the volcanic glass present in the ash to clay minerals

List Of Metals And Non Metals | Science Trends

Non Metals. Non – metals are materials not holding the characteristics of metals, means they are not shiny, hard, fusible, malleable, ductile, etc. Many materials like coal and Sulphur are very soft and dull in appearance. They break down into very fine thin powdery mass on tapping with the hammer.

Transition metal complexes are formed when transition metals are bonded to one or more neutral or negatively charged non-metal species, referred to as ‘ligands’. Without these bonds, all the d orbitals are equal in energy – however, once they are present, some d orbitals move to a higher energy than they were at before, whilst some move to a lower energy, creating an energy gap.
