Can you help me with electronegativity differences???

Question

Are the following ionic, non-polar covalent, or covalent???

1. HCl

2. MgO

3. NaCl

4. NaF

5. H2O

6. CaCl2

7. I2

8. O2

9. H2S

10. LiF

Answer 1

Oops! You forgot one possibility: Polar covalent! You see, non-polar covalent is covalent. In these answers, I shall correct you.

1. HCl polar covalent

2. MgO ionic

3. NaCl ionic

4. NaF ionic

5. H2O covalent (the ionization into H+ and OH- is minimal.

6. CaCl2 ionic

7. I2 covalent

8. O2 covalent

9. H2S covalent

10. LiF ionic
