Question Analysis
This question involves identifying the type of bonding in a given compound based on the elements involved.

Key Concept Explanation
Silicon (Si) is a metalloid (has properties of both metals and nonmetals), while oxygen (O) is a typical nonmetal. Bond formation between metalloids and nonmetals follows the rule for nonmetal-nonmetal combinations: they form covalent bonds by sharing electrons.

Option Analysis
1. Identify the elements in $$\text{SiO}_2$$: silicon (a nonmetal) and oxygen (a nonmetal).
2. Evaluate each option:
Option A: Incorrect. Ionic bonds require a metal-nonmetal combination. Si is a metalloid, not a metal, so no ions are formed.
Option B: Correct. Si and O share valence electrons to form covalent bonds, forming a network covalent lattice.
