Chem 511 Unit 4 Review: Ionic Bonding & Nomenclature

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.

Front

What is the general formula for naming ionic compounds?

Back

The name of the ionic compound is formed by naming the cation (metal) first, followed by the anion (nonmetal) with its ending changed to '-ide' or the appropriate polyatomic ion name.

Front

What is the significance of valence electrons in ionic bonding?

Back

Valence electrons are the electrons in the outermost shell of an atom. In ionic bonding, atoms transfer valence electrons to achieve a full outer shell, resulting in the formation of ions.

Front

How do you determine the charge of a monatomic ion?

Back

The charge of a monatomic ion is determined by the number of valence electrons it has. Metals typically lose electrons and become positively charged (cations), while nonmetals gain electrons and become negatively charged (anions).

Front

What is the difference between a cation and an anion?

Back

A cation is a positively charged ion formed when an atom loses one or more electrons, while an anion is a negatively charged ion formed when an atom gains one or more electrons.

Front

What is the formula for calcium phosphate?

Back

The formula for calcium phosphate is Ca3(PO4)2.

Front

How do you name the ionic compound LiBr?

Back

The ionic compound LiBr is named lithium bromide.

Front

What is the correct name for PbS2?

Back

The correct name for PbS2 is lead (IV) sulfide.

Front

What happens during the formation of an ionic bond?

Back

During the formation of an ionic bond, one atom donates electrons to another atom, resulting in the formation of oppositely charged ions that attract each other.

Front

What is a polyatomic ion?

Back

A polyatomic ion is a charged entity composed of two or more atoms bonded together, which can be either positively or negatively charged.
