To determine how many zinc (Zn) atoms are in the compound [tex]\( Zn \left( ClO_3 \right)_2 \)[/tex], let's analyze the compound step by step.
1. Identify the components of the compound:
- The compound [tex]\( Zn \left( ClO_3 \right)_2 \)[/tex] consists of one zinc (Zn) ion and two chlorate ([tex]\( ClO_3 \)[/tex]) ions.
2. Consider the subscript next to the zinc (Zn) symbol:
- The zinc (Zn) symbol does not have a subscript, which means there is only one zinc atom present in the formula unit.
Given this, we can conclude:
- Each molecule of [tex]\( Zn \left( ClO_3 \right)_2 \)[/tex] contains exactly 1 zinc (Zn) atom.
Therefore, the number of Zn atoms in [tex]\( Zn \left( ClO_3 \right)_2 \)[/tex] is:
[tex]\[
\text{1}
\][/tex]
So, the correct option is:
B. 1
