Questions about compounds?

Question

I need to know the follow about these compounds.
-Type of bond
-Electro negativity Calculation
-Electron Dot Configuration

Cl2 (small 2 under the L)

CO2(small 2 under the O)

Answer 1

Cl2 is a nonpolar covalent bond and CO2 is a polar covalent bond.

The electro negativity of Cl is 3.0, so the difference would be 0.

for CO2, C has an electronegativity of 2.6 and each O has an electronegativity of 3.4


for electron dot, put 2 dots between the 2 Cl. then, put 2 dots on top of each Cl, 2 dots on the side, and 2 dots on the bottom. If you add all the dots, they will equal to 14. This is the number they're supposed to equal to cause each Cl has 7 valence electrons.

for CO2, C would be in the center and the 2 oxygens would be placed on each side of the C. put 2 dots between O and C. and another 2 dots between C and O.

it would look something like this O:C:O

now, put 2 dots on top of each O and C and also put 2 on the side and the bottom.

your diagram would look like this with 2 dots on the bottom of each O and on the bottom of C, and with 2 dots on top of each O and on top of C: :O:C:O:

Answer 2

Covalent both.
