Tin is a chemical element; it has symbol Sn (from Latin stannum) ... The tin whistle is so called because it was mass-produced first in tin-plated steel. [92] [93]
Tin: English, from Proto-Germanic · Symbol Sn, from Latin stannum: 14 5 p-block 118.71: 7.265: 505.08: 2875: 0.228: 1.96: 2.3: primordial solid 51 Sb Antimony: Latin antimonium, of unclear origin: folk etymologies suggest Greek antí 'against' + mónos 'alone', or Old French anti-moine 'monk's bane', but could be from or related to Arabic ...
Tin-121m (121m Sn) is a radioisotope and nuclear isomer of tin with a half-life of 43.9 years. In a normal thermal reactor, it has a very low fission product yield; thus, this isotope is not a significant contributor to nuclear waste. Fast fission or fission of some heavier actinides will produce tin-121 at higher yields. For example, its yield ...
Charge carrier density, also known as carrier concentration, denotes the number of charge carriers per volume. In SI units, it is measured in m −3. As with any density, in principle it can depend on position. However, usually carrier concentration is given as a single number, and represents the average carrier density over the whole material.
Periodic tables usually at least show the elements' symbols; many also provide supplementary information about the elements, either via colour-coding or as data in the cells. The above table shows the names and atomic numbers of the elements, and also their blocks, natural occurrences and standard atomic weights. For the short-lived elements ...
This page shows the electron configurations of the neutral gaseous atoms in their ground states. For each atom the subshells are given first in concise form, then with all subshells written out, followed by the number of electrons per shell.
Women start losing muscle mass as early as their 30s. In fact, we lose about 3 to 5 percent per decade. But you can preserve the muscle mass you have—or even build more!—by lifting, even just ...
An even number of protons or neutrons is more stable (higher binding energy) because of pairing effects, so even–even nuclides are much more stable than odd–odd. One effect is that there are few stable odd–odd nuclides: in fact only five are stable, with another four having half-lives longer than a billion years.
