From the periodic table, what is the atomic number of aluminum? (a) 26.98 (b) 13 (c) 18 (d) 39.95 Elements: Elements are pure substances composed of only one type of atoms. They can exist in multiple isotopic forms which can vary in the number of neutrons affecting...
1 Despite the wealth of studies into technically challenging syntheses of uranium-element bonds and their attendant experimental and quantum chemical properties,2 there is a relative paucity of research into the fundamental nature of “terminal” (neither bridging nor tethered) actinide arene complexes....
The mass number of an atom is the total number of protons and neutrons contained within the nucleus of the atom. The number of protons determines the element and will always equal the atomic number of that element. The number of neutrons can change and will determine which isotope of that...
Lithium, atomic number 3, is an element of many uses. It's used in the manufacture of aircraft and in certain batteries. It's also used in mental health: Lithium carbonate is a common treatment of bipolar disorder, helping to stabilize wild mood swings caused by the illness. Lithium has...
The number of protons in an atom of any given element is always the same. Physicists call this the atomic number. So, in the above example of lead, its atomic number is 82 and that does not change; if it did, it would be a different element (thallium, atomic number 81, or bismuth...
You’ve probably heard of uranium-235 and, well, the polonium-210 that did in former KGB officer Alexander Litvinenko. The former is moderately radioactive, the latter horrendously so. But there are all sorts of stable6 isotopes, too. For example, silver comes in two of them, 107 and ...
