Question

What type of bond is produced between the following atoms and provide numerical evidence 1. Li and F2. CI and CI3 C and O4 CA and S

Answer 1

1. Ionic bond

2. Nonpolar covalent

3. Polar covalent

4. Polar covalent

Step-by-step explanation:

Depending on the difference of electronegativity between elements, bonds can be classified into:

- Nonpolar covalent: less that 0.4

- Polar covanlent: between 0.4 and 1.7

- Ionic: more that 1.7

In this case, we have to calculate the difference of electronegativity:

- Li electronegativity: 1

- F electronegativity: 4

- Cl electronegativity: 3.2

- C electronegativity: 2.6

- O electronegativity: 3.4

- Ca electronegativity: 1

- S electronegativity: 2.6

• Li and F:

4 - 1 = 3 (Ionic bond)

• Cl and Cl:

3.2 - 3.2 = 0 (Nonpolar covalent)

• C and O:

3.4 - 2.6 = 0.8 (Polar covalent)

• Ca and S:

2.6 - 1 = 1.6 (Polar covalent)
