Choose the set that goes from lowest to highest electronegativity?

• Cu, Mg, Sr, Ca
• F, Cl, Br, Si
• Cs, Rb, Ca, Mg
• Zn, Cd, Ag, Cu

Electronegativity is...

• how good an atom is at attracting electrons
• the ability of an atom to lose electrons
• the energy required to remove an electron from a specific atom
• how easy it is to make friends.

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
