Web3 sep. 2024 · While a neutral atom for scandium would have the same number of electrons as protons, the ion is shown to have a +3 charge. This means it has 3 fewer electrons than the neutral atom or 21 - 3 = 18 electrons. Answer The Sc 3+ ion contains 21 protons and 18 electrons. Protons and Electrons in Polyatomic Ions WebThis makes calcium a positive ion with a charge of 2+. Since each chlorine atom gained an electron, they each have 17 protons and 18 electrons. This makes each chloride a negative ion with a charge of −1. Oppositely charged ions attract each other, forming an ionic bond. The bonded ions are more stable than the individual atoms were.
