WebB. The atomic radius of main-group elements generally increases down a group because ________. A) nuclear charge increases down a group. B) nuclear charge decreases … WebThe general trend in atomic radius is that moving down the periodic table, the size increases; moving across the periodic table from left to right, the size decreases. Therefore, rubidium has the largest atomic radius whereas helium has the smallest.
WebSolution. Verified by Toppr. Correct option is B) ∙ As soap bubble is conductor, so by symmetry, the charge will distribute uniformly over the surface of bubble. ∙ Due to mutual repulsion between like charges over the surface, they will push the parts of soap film away from each other. ∙ Hence the radius of the bubble will Increase. WebNov 13, 2016 · Effective nuclear charge increases from left to right. As we go across the periodic table from left to right, protons are more massive than electrons, so adding one proton and one electron to obtain a new atom means that #bb(Z_("eff")uarr)#. Higher #Z_"eff"# means smaller radius. A new quantum level corresponds to the valence shell …
WebAug 14, 2024 · The increase in atomic size going down a column is also due to electron shielding, but the situation is more complex because the principal quantum number n is not constant. As we saw in Chapter 2, the size of the orbitals increases as n increases, provided the nuclear charge remains the same. In group 1, for example, the size of the … WebApr 14, 2024 · For the ZnO formed by the pyrolysis of the Zn-MOF precursor ( Figure 3 f-1), the size of the nanoparticles increases to approximately 25 nm, mainly because of the aggregation and growth of the nanoparticles at high temperatures.
WebAug 14, 2024 · The trend in bond energies is due to a steady decrease in overlap between the 1s orbital of hydrogen and the valence orbital of the halogen atom as the size of the halogen increases. The larger the atom to which H is bonded, the weaker the bond.
