Chemists have a handy way of talking amount these vast numbers of atoms—by using the rather unusual word mole. A mole of something (anything) has exactly 6.022 × 1023 particles in it, which is a short way of saying 602,200,000,000,000,000,000,000 or 602 billion trillion. This stran...
The chemical symbol for antimony is Sb, an unusual abbreviation using none of the letters in the elements name. This is common for elements known to different ancient civilizations. While the name antimony comes from Greek, the chemical symbol is based on the Latin name of stibium. ...

but is a straightforward consequence of the fact that the electron density accumulates in the vicinity of the covalent bond – especially for more polarisable halogens such as bromine and iodine. This redistribution of charge is accompanied by an ‘equatorial’ band of negative charge between these...
This unusual halogen, having the formula BrCl, is a dark red liquid having a boiling point of 5 [degrees] C, a density of 2.34 and vapor pressure of 30 psig at 20 [degrees] C. Disinfection, taste, & odor control Molecular complexes of OC and CIF and BrCl has been observed and char...
No unusual tools or equipment are needed to disassemble the typical plastic valve; with proper design considerations the seals and key parts can be replaced in the field with minimal downtime. The overall ease of service and installation does have its drawbacks, however, as most mechanical ...
If you look at the list of elements that are found in sea water, they are found here too (including teensy amounts of thallium, iodine. bromine, and about 80 other elements). Is it healthier for you? I'm not a doctor or nutritionist, but I would guess it is. For one thing, the...
