Electronegativity is a measurement of the ability of a nucleus to...

• attract bonding electrons
• attract other nuclei
• attract elenece in the non-valence energy levels

How many electrons are represented by a single straight line in a Lewis structure?

• 1
• 2
• 4
• 6

The most electronegative atom in the periodic table is:
