Question Analysis
This question involves the judgment of chemical bond types based on the types of bonded elements. The main focus is on identifying the element pair that meets the formation condition of covalent bond.

Key Concept Explanation
Covalent bonding occurs when two atoms share one or more pairs of electrons. The shared electrons are attracted to the nuclei of both atoms, which holds the atoms together in a covalent bond. And covalent bonds typically form between nonmetals.

Step-by-step Solution
1. Recall the conditions for covalent bonding: Typically form between nonmetals.
2. Determine ...
