How many valence electrons are in H2O?
Understand the Problem
The question is asking for the number of valence electrons in a water molecule (H2O). To find this, we can sum the valence electrons from each atom present in the molecule. Hydrogen has 1 valence electron and there are two hydrogen atoms, while oxygen has 6 valence electrons. Therefore, we can calculate the total.
Answer
8 valence electrons
The final answer is 8 valence electrons
Answer for screen readers
The final answer is 8 valence electrons
More Information
Water (H2O) has a total of 8 valence electrons: 6 from the oxygen atom and 1 from each of the two hydrogen atoms.
Tips
A common mistake is not accounting for both hydrogen atoms, each contributing 1 valence electron.
