Ions may be larger or smaller than the neutral atom, depending on the ion's electric charge. When an atom loses an electron to form a cation, the other electrons are more attracted to the nucleus, and the radius of the ion gets smaller. Similarly, when an electron is added to an atom, forming an anion, the added electron increases the size of the electron cloud by interelectronic repul… WebbPeriodic Table Atomic Radius in the Periodic Table of Elements The atomic radius of a chemical element is a measure of the size of its atom, usually, the distance from the … chales rancho da marchaWebb4 nov. 2024 · You may assume that the valences of the elements—the number of electrons with which an atom will bond or form—are those that can be derived by looking at the groups (columns) of the periodic table.
