Guida verificata passo dopo passo1
Recall that an atom is electrically neutral when it has an equal number of protons (positively charged) and electrons (negatively charged).
Understand that an anion is a type of ion that carries a negative charge.
Since the negative charge arises from an excess of electrons, anions must have more electrons than protons.
Therefore, any atom that is an anion will have a greater number of electrons compared to protons.
This means the true statement about all anions is: 'They have more electrons than protons.'
