How are atomic nuclei determined?

Properties of atomic nuclei (atomic mass, nuclear cross-sections) are determined by the number of protons and number of neutrons (neutron number). It must be noted, especially nuclear cross-sections may vary by many orders from nuclide with the neutron number N to nuclide with the neutron number N+1. For example, actinides with odd neutron number are usually fissile (fissionable with slow neutrons) while actinides with even neutron number are usually not fissile (but are fissionable with fast neutrons). Heavy nuclei with an even number of protons and an even number of neutrons are (due to Pauli exclusion principle) very stable thanks to the occurrence of ‘paired spin’. On the other hand, nuclei with an odd number of protons and neutrons are mostly unstable.

Where does the name "alum" come from?

For more information on the Visual Elements image see the Uses and properties section below. The name is derived from the Latin name for alum, 'alumen' meaning bitter salt. A vertical column in the periodic table. Members of a group typically have similar properties and electron configurations in their outer shell.

Who invented the method of obtaining pure aluminium?

It fell to the German chemist Friedrich Wöhler to perfect the method in 1827, and obtain pure aluminium for the first time by using sodium instead of potassium. Glossary. Atomic radius, non-bonded. Half of the distance between two unbonded atoms of the same element when the electrostatic forces are balanced.

How is aluminium made?

Most commercially produced aluminium is extracted by the Hall–Héroult process. In this process aluminium oxide is dissolved in molten cryolite and then electrolytically reduced to pure aluminium. Making aluminium is very energy intensive. 5% of the electricity generated in the USA is used in aluminium production.

Why is aluminum used as an alloy?

It is the second most malleable metal and the sixth most ductile. It is often used as an alloy because aluminium itself is not particularly strong. Alloys with copper, manganese, magnesium and silicon are lightweight but strong. They are very important in the construction of aeroplanes and other forms of transport.

What is the atomic number of aluminum?

Aluminium ( aluminum in American and Canadian English) is a chemical element with the symbol Al and atomic number 13. Aluminium has a density lower than those of other common metals, at approximately one third that of steel.

When was aluminium first used?

The history of aluminium has been shaped by usage of alum. The first written record of alum, made by Greek historian Herodotus, dates back to the 5th century BCE. The ancients are known to have used alum as a dyeing mordant and for city defense. After the Crusades, alum, an indispensable good in the European fabric industry, was a subject of international commerce; it was imported to Europe from the eastern Mediterranean until the mid-15th century.

What is the most abundant element in the Earth's crust?

In the Earth's crust, aluminium is the most abundant metallic element (8.23% by mass) and the third most abundant of all elements (after oxygen and silicon). A large number of silicates in the Earth's crust contain aluminium. In contrast, the Earth's mantle is only 2.38% aluminium by mass.

How much aluminum was produced in 1900?

Throughout the 20th century, the production of aluminium rose rapidly: while the world production of aluminium in 1900 was 6,800 metric tons, the annual production first exceeded 100,000 metric tons in 1916; 1,000,000 tons in 1941; 10,000,000 tons in 1971.

What is the most reflective metal?

Aluminium metal has an appearance ranging from silvery white to dull gray, depending on the surface roughness. A fresh film of aluminium serves as a good reflector (approximately 92%) of visible light and an excellent reflector (as much as 98%) of medium and far infrared radiation. Aluminium mirrors are the most reflective of all metal mirrors for the near ultraviolet and far infrared light, and one of the most reflective in the visible spectrum, nearly on par with silver, and the two therefore look similar. Aluminium is also good at reflecting solar radiation, although prolonged exposure to sunlight in air add wear to the surface of the metal; this may be prevented if aluminium is anodized, which adds a protective layer of oxide on the surface.
