Octet Rule

Front

What is the Octet Rule?

Back

The Octet Rule states that atoms tend to gain, lose, or share electrons in order to have eight electrons in their valence shell, achieving a stable electron configuration similar to that of noble gases.

Front

Why do atoms gain or lose electrons?

Back

Atoms gain or lose electrons to achieve a full valence shell, which provides stability and lowers their energy state.

Front

What happens to an atom that gains electrons?

Back

An atom that gains electrons becomes negatively charged and is called an anion.

Front

What happens to an atom that loses electrons?

Back

An atom that loses electrons becomes positively charged and is called a cation.

Front

Which group of elements satisfies the Octet Rule without bonding?

Back

Group 18 (Noble gases) satisfies the Octet Rule and does not bond with other atoms.

Front

How many valence electrons does Aluminum (Al) have?

Back

Aluminum (Al) has 3 valence electrons.

Front

How many electrons does Aluminum (Al) need to lose to achieve stability?

Back

Aluminum (Al) needs to lose 3 electrons to achieve stability.

Front

How many valence electrons does Phosphorus (P) have?

Back

Phosphorus (P) has 5 valence electrons.

Front

How many more electrons does Phosphorus (P) need to follow the Octet Rule?

Back

Phosphorus (P) needs 3 more valence electrons to follow the Octet Rule.

Front

What is a stable electron configuration?

Back

A stable electron configuration is achieved when an atom has a full valence shell, typically consisting of 8 electrons.
