Question Analysis
This question involves identifying the type of bonding based on electron behavior. The main focus is on determining which substance contains bonds formed by sharing of electrons, which is characteristic of covalent bonding.
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. Identify the elements in each compound:
A. BaO → barium (metal) + oxygen (nonmetal) → ionic bonding.
B. C₂H₂ → carbon and hydrogen are nonmetals → covalent bonding.
C. K...
