Explain, including electron configurations in your answer. To the upper right corner of the periodic table will generally have the smallerĮxceptions to the trend above, particularly among the transition metals.Īnd fluorine from smallest to largest atomic radius. Will generally have the larger atomic radius, while an element located closer The lower effective nuclear charge is expected to have the larger atomicĬan draw the following conclusion regarding the trend on the periodic table forĪn element located closer to the lower left corner of the periodic table Than magnesium's 12 protons, chlorine will have a greater effective nuclearĬharge to draw chlorine's valence electrons closer to the nucleus and, thus,Ĭhlorine is expected to have the smaller atomic radius, while magnesium with Will generally have a greater effective nuclear charge to draw the valenceĮlectrons closer to the nucleus and, thus, decrease the atomic radius. Of n for the valence electrons, the atom with the greater number of protons The periodic table do not have a difference in the value of n for the valenceĪlkaline earth metal magnesium and the halogen chlorine in the third row both Sodium has the larger value of n than the valence 2s electron in lithium, we wouldĮxpect sodium to have the larger atomic radius. For example, let us compare the twoĪlkali metals lithium and sodium, which have the following electron Larger value of n will generally have the larger atomic radius. Same group of the periodic table, an atom having valence electrons with the You can effortlessly find every single detail about the elements from this single Interactive Periodic table.Periodic table are known as transition metals.
