7.2: Effective Nuclear Charge - Chemistry LibreTexts
WebBromine. Chlorine. Sodium. Phosphorus. Correct answer: Chlorine. Explanation: The effective nuclear charge is the attractive charge a valence electron feels from the nucleus. As you move from left to right along a period, and more positive charges (protons) fill up the nucleus, the more attraction the valence electron feels. As you move down a ... WebJan 15, 2024 · As you go down a group, more shells are occupied by electrons, which increases the size of the atom. The more core electron shells an atom has, the larger the size of the atom, and the farther the valence electrons are from the nucleus, thus the valence electrons will experience less effective nuclear charge and will be easily lost.
