WebQ: Arrange the following atoms in order of decreasing (less negative) electron affinity: F, S, As, Bi,…. A: Click to see the answer. Q: Calculate the effective nuclear charge on a 7s, a 5f, and a 6d electron in a uranium atom. A: Effective nuclear charge: It is the nuclear charge minus the shielding (or screening) factor σ…. 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 …
