These examples are programmatically compiled from various online sources to illustrate current usage of the word 'strontium.' Any opinions expressed in the examples do not represent those of Merriam-Webster or its editors. 2023 The elements strontium and lithium will produce red light. Strontium has physical and chemical properties similar to those of its two vertical neighbors in the periodic table, calcium and barium. The metal forms a dark oxide layer when it is exposed to air. 2023 Older rock formations including granite are found to have more strontium than younger rocks like basalt, and this is reflected in the vegetation that grows around them. An alkaline earth metal, strontium is a soft silver-white yellowish metallic element that is highly chemically reactive. Bob Holmes, Smithsonian Magazine, 17 Aug. As described in the Introduction, the data tables for each molecule consist of a table of derived molecular constants followed by the spectral line table.These are ordered alphabetically by the atomic symbols. 2023 Before there was much human activity, the strontium isotope ratio shows that the caribou spent much of their summer along the coast. Molecular Constant and Spectral Line Tables. 2023 The group knew that in strontium ruthenate, electrons travel from atom to atom using one of three distinct channels. Richard Grant, Smithsonian Magazine, 24 Oct. 2023 By analyzing the strontium values in 162 of these rodents, the team was able to build up a strontium map of Alaska. Strontium reacts vigorously with water and its salts ignite spontaneously in air, imparting a brilliant crimson color often sought after in pyrotechnics. 2023 The museum’s director, a paleontologist named Patrick Druckenmiller, who contributed to the Kik study, says strontium isotypes in these rodents’ teeth offered the key mapping aid. When using an AA or an AE spectrometer, a scientist will obtain a line spectra, not continuous spectra. Its properties are intermediate between those for barium chloride, which is more toxic. As with all compounds of strontium, this salt emits a bright red colour in flame, and is commonly used in fireworks to that effect. It is a typical salt, forming neutral aqueous solutions. 2023 In a separate study, a different group of researchers-also based at CU Boulder-used lasers to hold strontium atoms in a single two-dimensional plane. Strontium chloride (SrCl 2) is a salt of strontium and chloride. Outlines the experimental sequence for cooling atoms from around 600 ✬ to sub-microkelvin temperatures, and shows the theoryĪnd examples of ultracold cloud analysis by absorption imaging.Recent Examples on the Web Meanwhile Wooller and his colleagues were looking at the strontium and other isotopes in Kik’s tusk. The production of line spectra by the atoms of an element indicate that an atom can radiate only a certain amount of energy. Each element has a different atomic spectrum. This line spectrum is called an atomic spectrum when it originates from an atom in elemental form. red flame: strontium nitrate or strontium carbonate. The spectrum appears in a series of lines called the line spectrum. In the context of this machine, the thesis explains the technicalities of vacuum and laser system construction, Although objects at high temperature emit a continuous spectrum. The relevant theory for the operation of a quantum gas experiment in general is presented, as wellĪs the peculiarities of working with strontium, and the calculation of a single-site single-atom detection scheme for strontium The thesis describes the design and construction of a new versatile strontium quantum gas machine with envisioned quantum
