Covalent Bonds and Oxygen Properties

The video explores whether molecular oxygen (O2) is covalent or ionic. It begins by identifying oxygen on the periodic table as a non-metal, leading to the conclusion that O2, composed of two non-metal oxygen atoms, forms a covalent bond. The video further examines the electronegativity of oxygen, which is 3.5 for both atoms, resulting in a zero difference. This indicates that O2 is a non-polar covalent compound. Dr. B concludes that molecular oxygen is non-polar covalent.

What type of bond is formed between two oxygen atoms in O2?

• Hydrogen

• Covalent

• Metallic

• Ionic

Why is O2 considered a covalent compound?

• Because it is formed between a metal and a non-metal

• Because it involves the transfer of electrons

• Because it involves the sharing of electrons between two non-metals

• Because it is formed between two metals
