A negatively charged ion formed by gaining electrons.

The anion formed from nitrogen with a -3 charge.

The charge on the strontium ion is +2.

Ions are atoms with a positive or negative charge due to the gain or loss of electrons.

The chemical formula for the compound sodium bromide, which consists of sodium ions (Na+) and bromide ions (Br-), is NaBr.

Chemical nomenclature is the naming system used for chemical compounds. It provides standard names for identifying specific chemical compounds.

Chemists prefer systematic names because these names accurately reflect the chemical composition of a compound, eliminating ambiguity.

The International Union of Pure and Applied Chemistry (IUPAC) developed the present system of inorganic chemical nomenclature, ensuring uniformity in chemical naming.

Most elements are represented by their single-letter or two-letter symbols.

Hydrogen, Nitrogen, Oxygen, Fluorine, Chlorine, Bromine, and Iodine exist naturally as diatomic molecules, meaning they consist of two atoms bonded together.

Common names are based on physical or chemical properties of a compound, not necessarily reflecting their exact chemical composition.

The anion formed from sulfur is the sulfide ion (S-2).

Strontium forms a cation with a +2 charge, meaning it loses two electrons to become a positively charged ion.

Barium forms an anion with a -2 charge, called the bariumide ion.

Group VA elements, also known as pnictogens, are likely to form ions with a -3 charge due to their electron configuration.

The correct formula for the compound formed by magnesium and oxygen is MgO. Magnesium forms a +2 ion (Mg2+) and oxygen forms a -2 ion (O2-), resulting in a 1:1 ratio.
