Ionic compounds-names and formulas

Front

What is an ionic compound?

Back

An ionic compound is a chemical compound composed of ions held together by electrostatic forces termed ionic bonding. They typically form between metals and nonmetals.

How do you name ionic compounds containing transition metals?

Back

Ionic compounds with transition metals are named by stating the metal's name followed by its oxidation state in Roman numerals in parentheses, and then the name of the nonmetal with its ending changed to '-ide' or the name of the polyatomic ion.

What is the formula for potassium phosphate?

Back

The formula for potassium phosphate is K3PO4.

Front

How do you determine the charge of a metal ion in an ionic compound?

Back

The charge of a metal ion can be determined by the total charge of the compound being neutral and the known charges of the nonmetals or polyatomic ions present.

Front

What is the name of the compound with the formula Al(NO3)3?

Back

The name of the compound Al(NO3)3 is Aluminum (III) nitrate.

Front

What is the significance of Roman numerals in naming ionic compounds?

Back

Roman numerals indicate the oxidation state of the metal ion in the compound, which is important for transition metals that can have multiple oxidation states.

Front

What is the name of Cr(NO2)3?

Back

The name of Cr(NO2)3 is chromium (III) nitrite.

Front

What is the formula for calcium carbide?

Back

The formula for calcium carbide is Ca2C.

Front

How do you write the formula for an ionic compound?

Back

To write the formula for an ionic compound, combine the symbols of the cation and anion, adjusting the subscripts to ensure the total charge is neutral.

Front

What is a polyatomic ion?

Back

A polyatomic ion is a charged entity composed of two or more atoms covalently bonded that can act as a single unit in a compound.
