WebLooking at group 1 for example, it seems that Zeff remains the same at 1 (i.e., the increase in number of shielding electrons is negated by the increase in protons), and consequently atomic radii increases. The nuclear charge does in fact increase down a group but the shielding effects of additional electrons counters the attractive force. WebUsually down any group, the increase in shielding effect outweighs the increase in nuclear charge effect. Effective nuclear charge decreases, there is an overall weaker attraction on the valence electrons and less energy is required to remove the electrons. Therefore ease of oxidation and chemical reactivity increases down group 2.
