Chapter 5 Test Review

Front

What is the Lewis dot structure?

Back

A diagram that shows the bonding between atoms of a molecule and the lone pairs of electrons that may exist in the molecule.

Front

What happens to electrons during the formation of ionic bonds?

Back

Electrons are transferred from one atom to another, resulting in the formation of cations and anions.

Front

What is an anion?

Back

An anion is a negatively charged ion that is formed when an atom gains electrons.

Front

What is a cation?

Back

A cation is a positively charged ion that is formed when an atom loses electrons.

Front

How do you determine the charge of an ion?

Back

The charge of an ion is determined by the difference between the number of protons and electrons in an atom.

Front

What is the formula for chromium nitrite?

Back

Cr(NO2)3.

Front

What is the correct order of writing ions in a chemical formula for an ionic compound?

Back

The positive ion (cation) is written first, followed by the negative ion (anion).

Front

What is the charge of aluminum when it has 13 protons and 10 electrons?

Back

Aluminum has a charge of +3 (Al^+3).

Front

What is the significance of subscripts in a chemical formula?

Back

Subscripts indicate the number of atoms of each element in a compound.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons, while covalent bonds involve the sharing of electrons.
