13. As one proceeds from left to right across a given period on the Periodic Table the electronegativities of the elements generally (A) decrease; (B) increase; (C) remain the same. 14. As one proceeds from fluorineto astatine in Group 7A the electronegativity (A) decreases and the atomic radius increases; (B) decreases and the atomic radius decreases; (C) increases and the atomic radius decreases; (D) increases and the atomic radius increases. 15. An atom of fluorine is smaller than an atom of oxygen. One possible explanation is that, compared with oxy gen, fluorine has (A) a smaller oxidation number; (B) a smaller atomic number; (C) a greater nuclear charge; (D) more unpaired electrons. 16. In Period 3, as the atomic numbers increase, the pattern according to which the properties of the elements change is (A) metal - metalloid - nonmetal - noble
