WebThe ionic radius is equal to half the distance between two interacting gas atoms. The hours vary from 30 p.m. to more than 200 p.m. In a neutral atom, the atomic and ionic radius is the same, despite the fact that many elements exist as anions or cations. 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…
