Chemistry, Chapter 6 & 7 Review

Front

What does it mean when an element forms an ion with a 2- charge?

Back

It means that the element has gained 2 electrons.

Front

What is the overall electric charge of ionic compounds?

Back

The overall electric charge of ionic compounds is 0.

Front

What is the name of group 2A on the periodic table?

Back

Group 2A is known as the alkaline earth metals.

Front

What is an anion?

Back

An anion is any atom or group of atoms that has a negative charge.

Front

What charge does a sulfur atom form when it becomes an ion?

Back

A sulfur atom forms a -2 charge when it becomes an ion.

Front

What is the difference between cations and anions?

Back

Cations are positively charged ions, while anions are negatively charged ions.

Front

How do ionic bonds form?

Back

Ionic bonds form through the transfer of electrons from one atom to another, resulting in the attraction between oppositely charged ions.

Front

What is the significance of the octet rule in ionic bonding?

Back

The octet rule states that atoms tend to gain, lose, or share electrons to achieve a full outer shell of 8 electrons, leading to stability.

Front

What are the properties of ionic compounds?

Back

Ionic compounds typically have high melting and boiling points, are soluble in water, and conduct electricity when dissolved or molten.

Front

What is the role of valence electrons in ion formation?

Back

Valence electrons are the outermost electrons that are involved in the formation of ions through loss or gain.
