WebOrganic Chemistry (CHEM211) Textbook Notes 8/22 - pgs. 1-13 Chemical bonding is the force that holds atoms together in molecules Octet rule: the tendency of atoms to gain or lose valence electrons to form ions with the noble-gas configuration The component atoms in ionic compounds exist as ions (ex: KCl, where both follow the octet rule) These have … In atomic physics, the effective nuclear charge is the actual amount of positive (nuclear) charge experienced by an electron in a multi-electron atom. The term "effective" is used because the shielding effect of negatively charged electrons prevent higher energy electrons from experiencing the full nuclear charge of the nucleus due to the repelling effect of inner layer. The effective nuclear charge experienced by an electron is also called the core charge. It is possible to determine the …
WebThe effective nuclear charge, Z eff, increases down a group which draws electrons closer towards the nucleus, decreasing atomic radius. The principal quantum number, n, of electron orbitals that increases down a group and due to the quantum mechanical nature of electrons, the radius of these electron orbitals increases with increasing n, thus ...

WebNote that while we often refer to the Z eff of a valence electron, we can calculate the Z eff for any electron by taking into account only the number of core electrons that are shielding. For example, consider a 2 s electron of Cl. For Cl, Z = 17 and the electron configuration is 1 s2 2 s2 2 p6 3 s2 3 p5. The only electrons that will shield a 2 ...
