WebFeb 6, 2024 · More protons are added, but the outer valence shell remains the same, so the positively charged nucleus draws in the electrons more tightly. But for the nonmetallic elements, the ionic radius increases because there are more electrons than protons. While the atomic radius follows a similar trend, ions may be larger or smaller than neutral atoms. WebTogether, the number of protons and the number of neutrons determine an element’s mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the … defending your catholic faith

One proton has a … WebSilicon has fewer protons than phosphorus, so it would have a weaker attraction for shared electrons, and be less electronegative. Nitrogen is above phosphorus in the periodic table, has one fewer electron shell, and a smaller atomic radius. So it would be more electronegative. Arsenic has a larger atomic radius and would therefore be less ...

WebSep 2, 2024 · For example, Oxygen has a smaller radius than Sulfur. When you move right the row, the element has larger nuclear charge (more protons) for the same number of energy shells. Therefore, each electron is pulled stronger and the radius decreases. For example, Fluorine has a smaller radius than Oxygen. WebThe electrons are thus attracted to the nucleus more strongly, and the atomic radius is smaller (this attraction is much stronger than the relatively weak repulsion between electrons). As you move down a column, there are more protons, but there are also more complete energy levels below the valence electrons. These lower energy levels shield ...
