<reasoning>

Identify compound elements

Chlorine dioxide contains chlorine and oxygen. Both elements are nonmetals.

Determine bond type

Compounds formed between nonmetals are covalent. They share electrons rather than transferring them.

Analyze naming prefixes

The prefix "di-" in dioxide indicates two oxygen atoms. No prefix on chlorine means one chlorine atom.

Write chemical formula

Combining one chlorine atom and two oxygen atoms yields the formula \(\text{ClO}_2\).

<answer>
A. Chlorine dioxide is a covalent compound. This is because both chlorine and oxygen are nonmetals, and bonds between nonmetals are covalent.

B. To determine the chemical formula, look at the prefixes in the name:

1. "Chlorine" has no prefix, indicating one chlorine atom (\(\text{Cl}\)).
2. "Dioxide" has the prefix "di-", indicating two oxygen atoms (\(\text{O}_2\)).

Combining these gives the chemical formula: \(\text{ClO}_2\).
