However, the particularly rapid capacity reduction owing to the … google contact lens research paperWebA higher effective nuclear charge causes greater attractions to the electrons, pulling the electron cloud closer to the nucleus which results in a smaller atomic radius. Down a group, the number of energy levels (n) increases, so there is a greater distance between the nucleus and the outermost orbital. This results in a larger atomic radius. 2. chicago fire season 4 episode 1 on nbc

"WebSodium has 11 protons and argon has 18 protons. Each time we add a proton to a the nucleus the electron (which are negatively charged) feel a greater attraction to the nucleus. Since valence electrons are all in the same level, they feel a greater attraction to the nucleus as we move across the period. " - Greater shielding effect lithium sodium
