Unformatted text preview: onegativity decreases down a column, so BaO has the largest electronegativity difference and is the most polar b. Which ion is larger, Rb+ or Sr2+ the two ions have the same number of electrons, but Sr2+ has more positive charge ; thus electrons are drawn closer to the nucleus and Sr2+ is smaller. c. In which molecule is the C-O bond stronger, CO or CO2 CO has a triple bond, CO2 has double bonds; more shared electrons make bonds shorter and stronger; thus CO will have the stronger bond. page 4...
