Classifiion of Matter | Boundless Chemistry
Each atom has an atomic nuer, which represents the nuer of protons that are in the nucleus of a single atom of that element. The periodic table of elements is ordered by ascending atomic nuer. The chemical elements are divided into the metals, the metalloids, and the non-metals.
Properties of Liquids - Purdue University
Surface Tension There is a force of attraction between molecules in liquids, and liquids can flow until they take on the shape that maximizes this force of attraction. Below the surface of the liquid, the force of cohesion (literally, "sticking together") between molecules is the same in all directions, as shown in the figure below.. Molecules on the surface of the liquid, however, feel a net

Steel Glossary | Glossary of Terms | Platts
This is sheet steel to which a thin, hot-dip, aluminium-silicon alloy coating has been applied. It is primarily used in appliions that must withstand or reflect heat and resist corrosion at temperatures that are higher than galvanized coatings can cope with. The silicon content is usually 5-11% and this promotes adherence of the coating to the substrate.

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.
