Information about words in this company name or address

h

The most common isotope of hydrogen is protium with a single proton and no neutrons. In ionic compounds it can take a negative charge , or as a positively charged species H+. The latter cation is written as though composed of a bare proton, but in reality, hydrogen cations in ionic compounds always occur as more complex species. Hydrogen forms compounds with most elements and is present in water and most organic compounds. It plays a particularly important role in acid-base chemistry with many reactions exchanging protons between soluble molecules. As the simplest atom known, the hydrogen atom has been of theoretical use. For example, as the only neutral atom with an analytic solution to the Schrödinger equation, the study of the energetics and bonding of the hydrogen atom played a key role in the development of quantum mechanics.

c

When the Roman alphabet was introduced into Britain, ‹c› represented only /k/ and this value of the letter has been retained in loanwords to all the insular Celtic languages: in Welsh, Irish, Gaelic, ‹c› represents only /k/. The Old English or "Anglo-Saxon" writing was learned from the Celts, apparently of Ireland; hence ‹c› in Old English also originally represented /k/; the Modern English words kin, break, broken, thick, and seek, all come from Old English words written with ‹c›: cyn, brecan, brocen, Þicc, and séoc. But during the course of the Old English period, /k/ before front vowels was palatalized, having changed by the tenth century to , though ‹c› was still used, as in circe, wrecca. On the continent, meanwhile, a similar phonetic change had also been going on .

In Vulgar Latin, /k/ became palatalized to in Italy and Dalmatia; in France and the Iberian peninsula, it became . Yet for these new sounds ‹c› was still used before front vowels the letter thus represented two distinct values. Subsequently, the Latin phoneme /kʷ/ de-labialized to /k/ meaning that the various Romance languages had /k/ before front vowels. In addition, Norman used the Greek letter ‹k› so that the sound /k/ could be represented by either ‹k› or ‹c› the latter of which could represent either /k/ or /ts/ depending on whether it preceded a front vowel or not.
