- Redirected from Aluminum. Aluminium or aluminum (in the U.S. and Canada) is a chemical element in the periodic table with the symbol Al and atomic number 13. A silvery, ductile metal, aluminium is found primarily as the ore bauxite and is remarkable for its resistance to oxidation, its strength, and its light weight. Aluminium is used in many industries to make millions of different products and is very important to the world economy.

Period 3 element Argon is the most abundant noble gas in Earth's crust, comprising 0.00015% of the crust. Nearly all of the argon in Earth's atmosphere is radiogenic argon-40, derived from the decay of potassium-40 in the Earth's crust. In the universe, argon-36 is by far the most common argon isotope, being the preferred argon isotope produced by stellar nucleosynthesis in supernovas.

What are the oldest elements? The oldest elements in the universe are also the simplest and most abundant: hydrogen and helium. They were first formed after the big bang approximately 14 billion years ago. All of the other elements were created in the cores of stars, which were formed several million years after the big bang event.

Astronomical unit For units in astronomy, see astronomical system of units. The astronomical unit (symbol au, AU or ua) is a unit of length, roughly the distance from the Earth to the Sun. However, that distance varies as the Earth orbits the Sun, from a maximum (aphelion) to a minimum (perihelion) and back again once a year.

Venus : distance in astronomical units? An astronomical unit (AU) is a measure of distance often used in astronomy, equal to the distance between the Earth and the Sun. In terms of more common units of measurement, an AU is equal to about 93 million miles (150 million km), or the distance light travels in a little over eight minutes. The symbol AU is most often used to represent the astronomical unit, though less commonly you may see UA used instead.

Aluminium Aluminium (or aluminum; see different endings) is a chemical element in the boron group with symbol Al and atomic number 13. It is a silvery-white, soft, nonmagnetic, ductile metal. Aluminium is the third most abundant element (after oxygen and silicon) in the Earth 's crust, and the most abundant metal there. It makes up about 8% by mass of the crust, though it is less common in the mantle below.

Abundance of the chemical elements The abundance of elements in the Sun and outer planets is similar to that in the universe. Due to solar heating, the elements of Earth and the inner rocky planets of the Solar System have undergone an additional depletion of volatile hydrogen, helium, neon, nitrogen, and carbon (which volatilizes as methane).

Introduction to the Chemical Elements Pure elements can be found as atoms, molecules, ions, and isotopes. So, examples of elements include a hydrogen atom (H), hydrogen gas (H2), the hydrogen ion H+, and isotopes of hydrogen (protium, deuterium, and tritium). The element with one proton is hydrogen. Helium contains two protons and is the second element.
