Problem: Using only the periodic table, rank the elements in each set in order of increasing atomic size: i) \( \mathrm{Se}, \mathrm{Br}, \mathrm{Cl} \) a) \( \mathrm{Br}<\mathrm{Cl}<\mathrm{Se} \) b) \( \mathrm{Se}<\mathrm{Br}<\mathrm{Cl} \) c) \( \mathrm{Cl}<\mathrm{Br}<\mathrm{Se} \) ii) I, Xe, Ba a) \( \mathrm{Ba}< \) I \( <\mathrm{Xe} \) b) \( \mathrm{Xe}<\mathrm{I}<\mathrm{Ba} \) c) I \( <\mathrm{Xe}<\mathrm{Ba} \)
