Electronegativity – use the values given to determine polar/non-polar/ionic compounds

Question 1

Non polar:

Answer 1

difference less than 0.5, electrons are shared equally

Question 2

Polar:

Answer 2

difference of 0.5-2.0, electrons are shared unequally, creating a dipole

Question 3

Ionic:

Answer 3

difference greater than 2.0, one atom donates an electron to the other, resulting in ions
