which has an electronegativity similar to oxygen?
chloride
nitrogen
carbon

Explanation:

Covalent bonds are crucial in biology as they form stable connections between atoms in biological molecules like proteins, nucleic acids, etc. Looking at the electronegativity values on the periodic - table (represented in the image), nitrogen has an electronegativity value close to that of oxygen. Oxygen has an electronegativity of approximately 3.5, and nitrogen has an electronegativity of around 3.0.

Answer:

Question 1: covalent
Question 2: nitrogen
