WebFeb 7, 2024 · Explanation: When an atom gains an electron, it becomes a negatively charged ion that we call an anion. Anions are larger in size than their parent atoms because they …
WebJul 3, 2024 · Ions are atoms or molecules which have gained or lost one or more valence electrons, giving the ion a net positive or negative charge. If the chemical species has more protons than electrons, it carries a net positive charge. If there are more electrons than protons, the species has a negative charge. WebAdult Education.

Webion, any atom or group of atoms that bears one or more positive or negative electrical charges. Positively charged ions are called cations; negatively charged ions, anions. Ions … WebSep 3, 2024 · Identify the number of protons and electrons in the Sc 3+ ion. Solution Use the Periodic Table to find the atomic number of Sc ( scandium ). The atomic number is 21, which means that scandium has 21 protons. While a neutral atom for scandium would have the same number of electrons as protons, the ion is shown to have a +3 charge.
