Aluminum's only stable form is Al-27, and most isotopes have half-lives of mere milliseconds, meaning they are gone in less than a blink of an eye. But Al-26, aluminum's longest-lasting radioactive isotope, has a half-life of about 730,000 years. This isotope is found in star-formi...
Using an energy-dependent geometric cross-section formula to calculate the expected number of primary nuclear interactions shows that the 12C + Al system has, within uncertainties, the same number of neutrons per interaction (0.99 +/- 0.03) as does the 4He + Al system (1.02 +/- 0.04), ...

Melting point: 660°C (1220°F). Boiling point: 2467°C (4473°F). Atomic number: 13 (one aluminum atom contains 13 protons, 13 electrons, and 14 neutrons). Relative atomic mass: 26.98.
What is the mass number of aluminum? How many grams are there in 1.30 x 10^24 atoms of silver? How many atoms of cobalt equal a mass of 58.93 g? How many valence electrons does a neutral atom of aluminum have? How many protons, neutrons, and electrons are in aluminum?
The number written to the right of the element's name is the mass number. The mass number represents the number of protons plus neutrons in the nucleus of an atom of the element. The number of protons determines the element, but the number of neutrons in the atom of any one element ...
weighing approximately one-third as much as an equal volume of copper or steel. It is corrosion-resistant, is an excellent conductor of heat and electricity, reflects both light and radiant heat, is nonmagnetic, does not readily absorb neutrons, can be safely used with foods and medicines, and...
A number of AlN etches have been reported in the literature. However, none of these etches has been performed on high-quality single-crystal AlN. The surface chemistry of AlN has been investigated by numerous techniques, including Auger electron spectroscopy, x-ray and ultraviolet photoemission ...
