electronegativity

What's the difference between electronegativity and electron affinity?

• Electronegativity is a measured energy value and electron affinity is a man-made number.
• Electron affinity is a measured energy value and electronegativity is a man-made number.

Which of the following is the least electronegative element?

• oxygen
• potassium
• fluorine
• nitrogen

Which of the following is the most electronegative element?

• nitrogen

Chlorine and Fluorine are both very electronegative, as they are both missing a single electron from their valence energy level.  Why is Fluorine more electronegative than Chlorine? 

• Fluorine has less energy levels.
• Chlorine has more electrons in its outer shell
• Fluorine has more protons.
• None of these
