Study Notes

Chemical nomenclature is the system used by chemists to identify compounds, with two classes of names: common and systematic.
Common names are arbitrary and based on outstanding properties, while systematic names precisely identify chemical composition.
Systematic names were devised by the International Union of Pure and Applied Chemistry (IUPAC).
Elements: most have formula equal to symbol, some are diatomic (H2, N2, O2, F2, Cl2, Br2, I2).
Two elements, sulfur and phosphorus, are commonly polyatomic.
Ions are formed by adding or removing electrons from atoms, forming cations (positive ions) or anions (negative ions).
Cations are named after their parent atoms (Na+ is sodium ion, Ca2+ is calcium ion).
Anions are named by adding –ide to the stem of the parent element (F- is fluoride ion, Cl- is chloride ion).
Ions formed by adding electrons are called anions, those formed by removing electrons are called cations.
A chemical compound must have a net charge of zero if it contains ions.
Write the formula for calcium chloride: CaCl2 (smallest numbers of Ca2+ and Cl- combine to make zero charge).
Write the formula for barium phosphide: BaP (smallest numbers of Ba2+ and P combine to make zero charge).
Systematic names precisely identify the chemical composition of a compound.
International Union of Pure and Applied Chemistry (IUPAC) devised the present system of inorganic chemical nomenclature.
Elements have symbols, some are diatomic (H2, N2, O2, F2, Cl2, Br2, I2).
Sulfur and phosphorus are common polyatomic elements.
Ions formed by adding electrons are called anions, those formed by removing electrons are called cations.
Cations are named after their parent atoms, anions are named by adding –ide to the stem of the parent element.
Write the formula for a compound by making sure the total charge is zero.
Calcium chloride formula: CaCl2.
Barium phosphide formula: BaP.
