Intro to Ionic Compounds

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 forms between metals and nonmetals.

What type of ion does phosphorus (#15) form?

Back

Phosphorus forms a -3 anion.

Front

Which elements typically form cations?

Back

Metals typically lose electrons to form positive ions (cations).

Front

What type of ion does selenium (#34) form?

Back

Selenium forms an anion.

Front

What is the charge of a cation?

Back

A cation has a positive charge.

Front

What is the charge of an anion?

Back

An anion has a negative charge.

Front

Which group of elements are known as nonmetals?

Back

Nonmetals include elements like hydrogen, carbon, nitrogen, oxygen, phosphorus, sulfur, and chlorine.

Front

What is the main characteristic of metals in terms of electron behavior?

Back

Metals tend to lose electrons to achieve a stable electron configuration.

Front

Which element gains electrons to form a negative ion?

Back

Nitrogen (#7) gains electrons to form a negative ion.

Front

What is the role of noble gases in ionic bonding?

Back

Noble gases are generally unreactive and do not form ions because they have a full valence shell.
