Simple Ionic Bonds

Front

What are ionic bonds?

Back

Ionic bonds are formed when valence electrons are transferred between atoms.

Front

Why do ionic bonds form?

Back

Ionic bonds form to fill the outermost energy level of atoms.

Front

What formula results when Ca⁺² and Br^- ions bond?

Back

The formula is CaBr₂.

Front

If an element has 3 valence electrons, what charge will likely form on its ion?

Back

The ion will likely have a charge of +3.

Front

A proton has what charge?

Back

A proton has a positive charge.

Front

What are valence electrons?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in forming bonds.

Front

What is the octet rule?

Back

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

Front

What is an anion?

Back

An anion is a negatively charged ion that has gained one or more electrons.

Front

What is a cation?

Back

A cation is a positively charged ion that has lost one or more electrons.

Front

How do ionic compounds typically form?

Back

Ionic compounds typically form between metals and nonmetals through the transfer of electrons.
