Ionic Compound Naming and Formula Units

Flashcards covering formula units, naming acids and bases, anion suffixes, and using Roman numerals for cations from the lecture transcript.

Formula unit

The smallest whole number ratio of ions present in an ionic crystal that leads to a neutral formula unit.

Acids

Compounds that get named using special acid rules.

Bases

Inorganic compounds that get named simply as ionic compounds.

Anion

An ion whose ending gets changed to an I suffix after dropping letters from the parent element name, without using a prefix to identify how many are present.

Roman numerals

Capital Roman numerals placed in parentheses at the end of the cation name (followed by a space) when cations have unknown oxidation.
