Webfact, this is exactly what the atomic radius trend looks like. Trends in Size: Atomic and Ionic Radius Both atomic and ionic radius follow the ENC arguments closely and without exception. The arguments are simple. The bigger the ENC, the more attraction to the nucleus and the small the atom or ion. The smaller the ENC, the smaller the ... WebApr 7, 2016 · Explanation: Effective nuclear charge is how attracted on particular electron is to the nucleus. It can be estimated by Zeff = Z −S where Zeff is the effective nuclear charge, Z is the atomic number and S is the number of "shielding" electrons.

Webaffinity indicates that an atom does not accept electrons as easily. Factors That Affect Electron Affinity There are two factors that can affect electron affinity. These are atomic size and nuclear charge. With regard to atomic size, let's think about a magnet and a refrigerator. When a magnet is closer to the surface of the WebA 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.
