Ionic Compounds and Nomenclature

These flashcards cover key concepts related to ionic compounds and their nomenclature, including definitions, examples, and characteristics.

Ionic Compounds

Composed of cations and anions, their formula is often the empirical formula, summing charges to equal zero.

Cation

A positively charged ion.

Anion

A negatively charged ion.

Electrical Neutrality

The principle that the total charge of the cation(s) must equal the total charge of the anion(s) in ionic compounds.

BaCl2

Barium chloride, an example of an ionic compound.

Roman Numerals in Nomenclature

Indicate the charge on metals in ionic compounds, especially transition metals.

Iron(II) chloride

An ionic compound represented as FeCl2, indicating iron has a +2 charge.

Nitride

The anion formed from nitrogen, with a charge of 3-.

Hydroxide

An anion (OH-) formed from oxygen and hydrogen, found in bases.

Phosphate

A polyatomic anion with the formula PO4, commonly found in various ionic compounds.

Mercury(I) Nitrite

The compound Hg2(NO2)2, formed from diatomic mercury with a +1 charge and nitrite anion.

Stock System

Nomenclature system used to indicate the charge of transition metals in ionic compound names.

Sulfide

The anion formed from sulfur, with a charge of 2-.

Calcium Phosphate

An ionic compound represented as Ca3(PO4)2, requiring a balance of cation and anion charges.
