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. WebChemistry questions and answers. (1) The effective nuclear charge is identical for all s and p orbitals in noble gases. (2) In lithium, all three electrons experience an identical effective nuclear charge. (3) In a hydrogen atom with only one electron, the 2s and 2p orbitals have the same energy. 2 and 3 O 3 only О 1 and 3 2 only O 1 only.

Nuclear Charge - The Periodic Table of Elements

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 … WebQ: Arrange the following atoms in order of decreasing (less negative) electron affinity: F, S, As, Bi,…. A: Click to see the answer.
