Bongkrek acid Name sounds like a combination of English words related to recreational drugs: bong; crack, a preparation of cocaine; and acid, a street name for lysergic acid diethylamide. Constipatic Acid: Some Australian lichens, like Parmelia constipata, have this as a component. Protoconstipatic acid, dehydroconstipatic acid, and methyl ...
The official summary chart of the IPA, revised in 2020. The International Phonetic Alphabet (IPA) is an alphabetic system of phonetic notation based primarily on the Latin script. It was devised by the International Phonetic Association in the late 19th century as a standard written representation for the sounds of speech. [1]
Double articulation [2] refers to the twofold structure of the stream of speech, which can be primarily divided into meaningful signs (like words or morphemes), and then secondarily into distinctive elements (like sounds or phonemes). For example, the meaningful English word "cat" is composed of the sounds /k/, /æ/, and /t/, which are ...
A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z). [ 1 ] The definitive visualisation of all 118 elements is the periodic table of the elements , whose history along the principles of the periodic law was one of the founding ...
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 ...
The following is the chart of the International Phonetic Alphabet, a standardized system of phonetic symbols devised and maintained by the International Phonetic Association. It is not a complete list of all possible speech sounds in the world's languages, only those about which stand-alone articles exist in this encyclopedia.
The English word yes, for example, consists of a palatal glide followed by a monophthong rather than a rising diphthong. In addition, the segmental elements must be different in diphthongs [ii̯] and so when it occurs in a language, it does not contrast with [iː]. However, it is possible for languages to contrast [ij] and [iː]. [20]
Small symbols pack in additional information: solid/liquid/gas, the color of an element, common in the human body, common in the earth's crust, magnetic metals, noble metals, radioactive, and rare or never found in nature. It does not overload kids with a lot of detailed numbers, like atomic weights and valence numbers.
