Caesium (IUPAC spelling; [9] also spelled cesium in American English) is a chemical element; it has symbol Cs and atomic number 55. It is a soft, silvery-golden alkali metal with a melting point of 28.5 °C (83.3 °F; 301.6 K), which makes it one of only five elemental metals that are liquid at or near room temperature .
sulphur vs sulfur: sulphur is the prevalent spelling outside North America; however, in scientific literature sulfur should be used, as recommended by IUPAC. (see Sulfur#Spelling and etymology) caesium vs cesium: cesium is the prevalent spelling throughout North America; however, in scientific literature caesium should be used, as recommended ...
Seriously though, cesium may be more common (one reason being that Americans have more scientific influence that any other nation, so cesium would naturally occur more frequently - even in non-English speaking nations), but the fact is that it is recommended by the appropriate international body to spell it caesium (maybe due to to historical ...
"Majority of English speakers clearly recognize Cesium better than Caesium" - possibly, but as a geochemist for 45 years I spell it caesium, as does my wife (an organometallic researcher) and people I work with from a number of English-speaking countries (Britain, South Africa, Australia) as well as English journals (eg Nature) and European ...
Caesium fluoride has the halite structure, which means that the Cs + and F − pack in a cubic closest packed array as do Na + and Cl − in sodium chloride. [3] Unlike sodium chloride, caesium fluoride's anion is smaller than its cation, so it is the anion size that sterically inhibits larger coordination numbers than six under normally ...
Gallium is one of the four non-radioactive metals (with caesium, rubidium, and mercury) that are known to be liquid at, or near, normal room temperature. Of the four, gallium is the only one that is neither highly reactive (as are rubidium and caesium) nor highly toxic (as is mercury) and can, therefore, be used in metal-in-glass high ...
The spell check feature is very useful when composing emails. You can improve its efficiency and reduce the number of reported misspellings by maintaining your personal dictionary in Desktop Gold. The words you add in your personal dictionary will not be flagged when you click the spell check button.
All element articles and their infoboxes use IUPAC spelling of elements and compounds. Notably, that is aluminium, sulfur, caesium, not aluminum, sulphur, cesium. For other English variant words (vapor vs. vapour) the infobox reads |engvar=. The parameter should be set in the article, and has options: en-US (or blank; default), en-GB, en-OED.
