Certainly! Let's determine the standard state formulas for fluorine, uranium, and xenon.
### Fluorine
Fluorine in its standard state exists as a diatomic molecule and is a gas. The chemical formula for fluorine in its standard state is:
[tex]\[ \text{Fluorine} \rightarrow F_2 (g) \][/tex]
### Uranium
Uranium in its standard state is a solid. The chemical formula for uranium in its standard state is:
[tex]\[ \text{Uranium} \rightarrow U (s) \][/tex]
### Xenon
Xenon in its standard state is a monatomic gas. The chemical formula for xenon in its standard state is:
[tex]\[ \text{Xenon} \rightarrow Xe (g) \][/tex]
With these formulas, the table can be completed as follows:
[tex]\[
\begin{tabular}{|c|c|}
\hline
element & formula \\
\hline
iron & Fe (s) \\
\hline
fluorine & F_2 (g) \\
\hline
uranium & U (s) \\
\hline
xenon & Xe (g) \\
\hline
\end{tabular}
\][/tex]
So, the completed table is:
[tex]\[
\begin{tabular}{|c|c|}
\hline
element & formula \\
\hline
iron & Fe (s) \\
\hline
fluorine & F_2 (g) \\
\hline
uranium & U (s) \\
\hline
xenon & Xe (g) \\
\hline
\end{tabular}
