9. 4. Types of Bonds
What type of bond would exist between atoms with electronegativity values of 3.0 and 2.6 ?

10. The electronegativity difference will be 3.0 – 2.6 = 0.4
4. Types of Bonds
The electronegativity difference will be 3.0 – 2.6 = 0.4
So that is a nonpolar covalent bond (A difference of 0.5 or more is polar covalent.)

11. 5. Types of Bonds
Why does water have a much higher melting point than carbon dioxide even though carbon dioxide is heavier?

12. Water is polar while CO2 is nonpolar.
5. Types of Bonds
Water is polar while CO2 is nonpolar.
It will take more energy to separate the water molecules from each other since the molecules are polar because the water molecules have a stronger attraction for one another.
