The letter compared with E/e, in fonts Arial, Times New Roman, Cambria, and Gentium Plus. Ǝ ǝ (turned E or reversed E) is an additional letter of the Latin alphabet used in African languages using the Pan-Nigerian alphabet. The minuscule is based on a rotated e and the capital form majuscule Ǝ, based on a reversed (mirrored) majuscule E.
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 table of the chemical elements showing the most or more commonly named sets of elements (in periodic tables), and a traditional dividing line between metals and nonmetals. The f-block actually fits between groups 2 and 3 ; it is usually shown at the foot of the table to save horizontal space.
4 Line feed is used for "end of line" in text files on Unix / Linux systems. 5 Carriage Return (accompanied by line feed) is used as "end of line" character by Windows, Classic Mac OS, MsDOS, and most minicomputers other than Unix- / Linux-based systems 6 Control-O has been the "discard output" key. Output is not sent to the terminal, but ...
Chemical symbols are the abbreviations used in chemistry, mainly for chemical elements; but also for functional groups, chemical compounds, and other entities. Element symbols for chemical elements, also known as atomic symbols, normally consist of one or two letters from the Latin alphabet and are written with the first letter capitalised.
A period on the periodic table is a row of chemical elements. All elements in a row have the same number of electron shells. Each next element in a period has one more proton and is less metallic than its predecessor. Arranged this way, elements in the same group (column) have similar chemical and physical properties, reflecting the periodic law.
Backwards E may refer to: Ǝ, a letter used in several alphabets, such as Pan-Nigerian or the African Reference Alphabet; ɘ, the IPA symbol for the close-mid central unrounded vowel; ∃, a symbol that is used to represent existential quantification in predicate Logic
