What is meant by an effective nuclear charge? Orem, W. H., and R. B. Finkelman. We learned that effective nuclear charge is the positive charge felt by the outermost electrons in an . Fluorine and chlorine are fairly abundant while bromine and iodine are comparatively less abundant. Trend-wise, as one progresses from left to right across a period, the electron affinity will increase as the nuclear charge increases and the atomic size decreases resulting in a more potent force of attraction of the nucleus and the added electron.

In effect, they shield or screen the valence electrons partially from the positive nuclear charge. Our table of Clementi-Raimondi effective nuclear charge has over 800 values covering 85 elements. Since electrons are the subatomic particle in question, not protons, the number of shielding electrons is {eq}18 - 8 = 10 {/eq}. Effective nuclear charge per electron is reduced and the electron cloud is held less tightly by the nucleus. The atomic size, however, is larger for chlorine than it is for fluorine because chlorine has three energy levels (chlorine is in period 3).
