It makes sense that as you add electrons to a given nucleus, the particle gets larger. Electrostatic forces of attraction arise between the nucleus and the electrons. Because chlorine is in the same period as phosphorus and sodium, but has the most protons in its shell (the most right within the same period) it has the greatest effective nuclear charge. The effective nuclear charge is the net charge an electron experiences in an atom with multiple electrons. 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. Oxford: Oxford University Press, 1998. Week 36 . This is because the number of core electrons is the same, therefore the shielding effect is constant.
