WebAs shown in Figure 6.31, as we move across a period from left to right, we generally find that each element has a smaller covalent radius than the element preceding it.This might seem counterintuitive because it implies that atoms with more electrons have a smaller atomic radius. This can be explained with the concept of effective nuclear charge, Z eff. WebQuestion: 8.34 How does atomic radius change (a) from left to right across a period and (b) from top to bottom in a group? Define ionic radius. Define ionic radius. How does the size of an atom change when it is converted to (a) an anion and (b) a 8.35 cation? WebNotice that, within the series of positive ions, and the series of negative ions, that the ionic radii fall as you go across the period. We need to look at the positive and negative ions separately. The positive ions In each case, the ions have exactly the same electronic structure - they are said to be isoelectronic. cummins career page
