Question

Electronegativity increases as the size of the atom increases. a. True b. False

Answer 1

B. False. Electronegativity is the property of an atom or element to attract electrons during a chemical reaction. If you look at the periodic trend for electronegativity you see Flourine has the highest electronegativity and Francium is the lowest. However, Francium has the largest atomic radius and Fluorine has the smallest (aside from Hydrogen and Helium). So your statement is false. The relationship between atomic radius and electronegativity is inversely proportional so a true statement would be: As atomic radius increases, electronegativity decreases.
