Nomenclature in Chemistry

Flashcards covering key concepts and vocabulary related to the nomenclature and formula writing in chemistry.

Ionic Compounds

Compounds composed of ions held together by electrostatic forces.

Anion

A negatively charged ion.

Cation

A positively charged ion.

Naming Ionic Compounds

For binary ionic compounds, name the anion (non-metal) with the suffix -ide and the cation (metal) first.

Exceptions in Naming Anions

Some anions have specific names, e.g., azote becomes nitrure instead of azoture.

Molecular Compounds

Compounds formed by covalent bonds between non-metals.

Prefixes in Molecular Naming

Use prefixes (mono-, di-, tri-, tetra-, etc.) to indicate the number of atoms in molecular compounds.

Dihydrogen Monoxide

Common name for water (H2O).

Chemical Formula of Ionic Compounds

Formed by combining the cation and anion, ensuring overall neutrality.

Cross Multiplication Method

A technique used to derive the formula from the ions' charges.

Pentachloride

A molecular compound consisting of five chlorine atoms and another element.

Simplicity in Formulas

In chemical formulas, indices of 1 are omitted.
