Question

HELP PLEASE, I GIVE 50 POINTS!!!!!!

How is the electronegativity difference used in determining the type of bond that occurs between two atoms? (SELECT ALL THAT APPLY)

a) If the difference is between 0.4 and 1.7, it is polar covalent.
b) If the difference is greater than 1.7, it is mostly ionic.
c) If the difference is zero, the bond is considered nonpolar covalent.
d) If the difference is less than 0.4, it is mostly covalent.
e) If the difference is zero, the bond is considered mostly polar.
f) If the difference is greater than 1.7, it is polar covalent.
g) If the difference is between 0.4 and 1.7, it is nonpolar covalent.
h) If the difference is less than 0.4, it is mostly ionic.

Answer 1

The best choices are,
A.)If the difference is between 0.4 and 1.7, it is polar covalent.
B.)If the difference is greater than 1.7, it is mostly ionic.
D.) If the difference is less than 0.4, it is mostly covalent.

Answer 2

The electronegativity difference between two atoms gives the type of bond that forms. If the difference is greater than 1.7, the bond is ionic. If the difference is between 0.4 and 1.7, the bond is polar covalent. If the difference is less than 0.4, the bond is nonpolar covalent.
