What is the valence number of oxygen?
Understand the Problem
The question is asking about the valence number of oxygen, which refers to the number of electrons in the outer shell of an oxygen atom that can participate in bonding. Oxygen typically has a valence number of 2, as it needs two more electrons to complete its outer shell.
Answer
2
The final answer is 2.
Answer for screen readers
The final answer is 2.
More Information
Oxygen has a valency of 2, meaning it usually gains or shares two electrons to achieve a stable electron configuration.
Tips
A common mistake is to confuse valence electrons with valency. Valence electrons are the electrons in the outer shell, while valency is the ability of the atom to bond, usually equal to the number of electrons needed to complete the outer shell.
