Ionic 2 Flashcard

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. It typically consists of a metal and a non-metal.

Front

How do you name ionic compounds?

Back

Ionic compounds are named by stating the name of the cation (metal) first, followed by the name of the anion (non-metal) with its ending changed to '-ide' for simple ions.

Front

What is the oxidation number?

Back

The oxidation number is a value that represents the total number of electrons that an atom either gains or loses in order to form a chemical bond.

Front

How do you determine the oxidation state of an element in a compound?

Back

To determine the oxidation state, consider the charges of the ions in the compound and the overall charge of the compound.

Front

What is the oxidation number of oxygen in most compounds?

Back

The oxidation number of oxygen is usually -2 in most compounds.

Front

What is the charge of cesium in cesium sulfide (Cs2S)?

Back

The charge of cesium in cesium sulfide is +1.

Front

What is the formula for the ionic compound formed between chromium (Cr) and oxygen (O)?

Back

The formula is Cr2O3, indicating that two chromium ions bond with three oxide ions.

Front

What is the charge of lead in lead(IV) iodide?

Back

The charge of lead in lead(IV) iodide is +4.

Front

What is the name of SnSe2?

Back

The name of SnSe2 is Tin(IV) Selenide.
