Question

question 26 (3 points) state whether each bond is ionic, polar covalent, or non - polar covalent hydrogen and chlorine potassium and bromine carbon and oxygen 1. ionic 2. polar covalent nitrogen and nitrogen 3. non - polar covalent hydrogen and sulfur lithium and fluorine

Explanation:

1. For Hydrogen and Chlorine: The electronegativity difference is significant but not large enough for an ionic bond. So it's polar covalent.
2. For Potassium and Bromine: There is a large electronegativity difference, with potassium being a metal and bromine a non - metal, forming an ionic bond.
3. For Carbon and Oxygen: There is an electronegativity difference causing unequal sharing of electrons, so it's polar covalent.
4. For Nitrogen and Nitrogen: Since the atoms are identical, there is equal sharing of electrons, resulting in a non - polar covalent bond.
5. For Hydrogen and Sulfur: There is a small electronegativity difference, leading to a polar covalent bond.
6. For Lithium and Fluorine: With a large electronegativity difference and lithium being a metal and fluorine a non - metal, it forms an ionic bond.

Answer:

Hydrogen and Chlorine: 2. Polar Covalent
Potassium and Bromine: 1. Ionic
Carbon and Oxygen: 2. Polar Covalent
Nitrogen and Nitrogen: 3. Non - polar Covalent
Hydrogen and Sulfur: 2. Polar Covalent
Lithium and Fluorine: 1. Ionic
