Metallic bonding - Wikipedia

Metallic bonding is a type of chemical bonding that arises from the electrostatic attractive force between conduction electrons (in the form of an electron cloud of delocalized electrons) and positively charged metal ions. It may be described as the sharing of free electrons among a structure of positively charged ions ().Metallic bonding accounts for many physical properties of metals, such

Liquid rocket propellant - Wikipedia

On March 16, 1926, Robert H. Goddard used liquid oxygen (LOX) and gasoline as rocket fuels for his first partially successful liquid-propellant rocket launch. Both propellants are readily available, cheap and highly energetic. Oxygen is a moderate cryogen as air will not liquefy against a liquid oxygen tank, so it is possible to store LOX briefly in a rocket without excessive insulation.

Revision Guide: 4.1 Atomic Structure and the Periodic Table

The mass nuer is the total nuer of protons and neutrons in the atom.

Non-metallic oxides – Notes Read

Jun 24, 2020· Non-metallic oxides are binary coinations of a non-metal with oxygen, in which oxygen uses the oxidation nuer -2. For its nomenclature we will preferably use: Stoichiometric nomenclature: it consists of putting before the word “oxide” a prefix that indies the nuer of oxygens followed by “de” and the name of the nonmetal with a

Silvery grey iron filings are added to yellow sulphur powder in a test tube. The contents of the test tube were strongly heated until they glowed red without further heating to form a dark grey dull solid.

Mean coordination nuers and the non-metal–metal

The value of N 1 has recently been proposed to play an important role in the non-metal–metal transition of mercury and other metal-atom clusters; it follows that an icosahedral cluster might be ‘more metallic’ than a cuboctahedral one with the same nuer of atoms, a consequence which should readily be testable experimentally.

Some examples of non-ferrous metals are aluminum, aluminum alloys, and copper, which are often used in industrial appliions such as gutters

Metal - Wikipedia

A metal (from Greek μέταλλον métallon, "mine, quarry, metal") is a material that, when freshly prepared, polished, or fractured, shows a lustrous appearance, and conducts electricity and heat relatively well. Metals are typically malleable (they can be hammered into thin sheets) or ductile (can be drawn into wires). A metal may be a chemical element such as iron; an alloy such as
