Question Analysis
This question involves a comparison between an ionic compound (NaCl) and a covalent compound (H₂O). The main focus is on analyzing bonding type, electron behavior, and resulting physical properties.

Key Concept Explanation
NaCl forms through ionic bonding involving electron transfer.
H₂O forms through polar covalent bonding involving unequal sharing of electrons.
Differences in bonding lead to differences in physical properties such as melting point, conductivity, and solubility.

Step-by-step Solution
1. Type of bonding
NaCl: Ionic bonding between Na⁺ and Cl⁻.
H₂O: Polar covalent bonding between H and O atoms.

2. Electron behavior
NaCl: Sodium loses one electron. Chlorine gains one electron. Electrons are transferred, forming ions.
H₂O: Electrons are shared unequally between hydrogen an...
