To determine the number of electrons in the chloride ion (
), we need to consider the number of electrons in a neutral chlorine atom and then account for the additional electron gained due to the negative charge.1. **Number of electrons in a neutral chlorine atom:** - Chlorine has an atomic number of 17, which means a neutral chlorine atom has 17 electrons.2. **Effect of the negative charge:** - The
charge indicates that the ion has gained one additional electron compared to the neutral atom.Therefore, the total number of electrons in the
ion is:
So, the correct answer is:
