Saudi Vision 2030 is a Saudi Arabian government program launched by Crown Prince Mohammed bin Salman in January 2016. The program aims to diversify the Saudi economy away from oil, in addition to transforming the country both socially and culturally. [1] This following is a list of all projects that were announced as part of Vision 2030: [2]
Compounds with a positive ion : The name of the compound is simply the cation's name (usually the same as the element's), followed by the anion. For example, NaCl is sodium chloride, and CaF 2 is calcium fluoride. Cations of transition metals able to take multiple charges are labeled with Roman numerals in parentheses to indicate their charge.
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 ...
A chemical formula is a way of presenting information about the chemical proportions of atoms that constitute a particular chemical compound or molecule, using chemical element symbols, numbers, and sometimes also other symbols, such as parentheses, dashes, brackets, commas and plus (+) and minus (−) signs.
The compound BaO, which is composed of Ba 2+ cations and O 2− anions, is referred to as barium oxide. The oxidation state of each element is unambiguous. When these ions combine into a type-I binary compound, their equal-but-opposite charges are neutralized, so the compound's net charge is zero.
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.
This complements alternative listing at list of inorganic compounds. There is no complete list of chemical compounds since by nature the list would be infinite. Note: There are elements for which spellings may differ, such as aluminum/aluminium, sulfur/sulphur, and caesium/cesium.
These are in the form of RE a M b Pn c, where M is a carbon group or boron group element and Pn is any pnictogen except nitrogen. These compounds are between ionic and covalent compounds and thus have unusual bonding properties. [4] These elements are also noted for their stability in compounds due to their tendency to form covalent double ...
