Using only the periodic table arrange the following elements in order of increasing atomic radius: strontium, rubidium, xenon, tin Smallest|| Largest Please answer this question according to the general rules you have learned regarding periodic trends. DO NOT base your answer on tabulated values since exceptions may occur.

What trend in atomic radius occurs as you go down a group on the periodic table? Explain why this occurs.

Each of the statements below attempts to explain why some periodic property varies predictably among elements in the periodic table. Determine if each statement is true or false. Within a period, elements with higher atomic numbers have atoms of smaller radius because the valance electrons are in higher principal energy levels. Within a family, elements with higher atomic numbers have lower ionization energy because the valance electrons are in higher principal energy levels. Within a period, elements with higher atomic numbers have higher ionization energy because the valance electrons are in higher principal energy levels. Within a family, elements with higher atomic numbers have higher electronegativity because the atoms have higher effective nuclear charge. Within a period, elements with lower atomic numbers require more energy to remove an electron from the atom, because the valance electrons are in higher principal energy levels. Within a period, elements with lower atomic…

Without using a periodic table, give the ground-state electron configuration and block designation (s-, p-, d-, or f-block) of an atom with (a) 17 electrons, (b) 37 electrons, and (c) 22 electrons. Classify each atom as a main group element or transition metal.
