Although most compounds are referred to by their IUPAC systematic names (following IUPAC nomenclature), traditional names have also been kept where they are in wide use or of significant historical interests.
Bettelheim et al. The nonmetals are distinguished based on the molecular structures of their most thermodynamically stable forms in ambient conditions. [5] Polyatomic nonmetals form structures or molecules in which each atom has two or three nearest neighbours (carbon: C x; phosphorus: P 4; sulfur: S 8; selenium: Se x); diatomic nonmetals form molecules in which each atom has one nearest ...

Inorganic compounds exhibit a range of bonding properties. Some are ionic compounds, consisting of very simple cations and anions joined by ionic bonding.Examples of salts (which are ionic compounds) are magnesium chloride MgCl 2, which consists of magnesium cations Mg 2+ and chloride anions Cl −; or sodium hydroxide NaOH, which consists of sodium cations Na + and hydroxide anions OH −.
Being a metalloid, most of its chemistry is nonmetallic in nature. Boron is a poor oxidizing agent (B 12 + 3e → BH 3 = –0.15 V at pH 0). While it bonds covalently in nearly all of its compounds, it can form intermetallic compounds and alloys with transition metals of the composition M n B, if n > 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.
In 1802 the term "metalloids" was introduced for elements with the physical properties of metals but the chemical properties of non-metals. [194] However, in 1811, the Swedish chemist Berzelius used the term "metalloids" [195] to describe all nonmetallic elements, noting their ability to form negatively charged ions with oxygen in aqueous ...
An inorganic compound is typically a chemical compound that lacks carbon–hydrogen bonds — that is, a compound that is not an organic compound. [ 1 ] [ 2 ] The study of inorganic compounds is a subfield of chemistry known as inorganic chemistry .
