Transcript text: Write a complete chemical formula, including physical state symbol, for each element listed below in its standard state. The first row of the table has been completed for you. \begin{tabular}{|c|c|} \hline element & formula \\ \hline iron & $\mathrm{Fe}(s)$ \\ \hline nitrogen & $\square$ \\ \hline potassium & $\square$ \\ \hline thorium & $\square$ \\ \hline \end{tabular}

Solution

Solution Steps

Step 1: Determine the Standard State of Nitrogen

Nitrogen is a diatomic molecule in its standard state. It exists as a gas under standard conditions.

Step 2: Determine the Standard State of Potassium

Potassium is a metal and exists as a solid in its standard state.

Step 3: Determine the Standard State of Thorium

Thorium is a metal and exists as a solid in its standard state.

Final Answer

\[ \begin{array}{|c|c|} \hline \text{element} & \text{formula} \\ \hline \text{iron} & \mathrm{Fe}(s) \\ \hline \text{nitrogen} & \mathrm{N}_2(g) \\ \hline \text{potassium} & \mathrm{K}(s) \\ \hline \text{thorium} & \mathrm{Th}(s) \\ \hline \end{array} \]

Nitrogen: $\boxed{\mathrm{N}_2(g)}$
Potassium: $\boxed{\mathrm{K}(s)}$
Thorium: $\boxed{\mathrm{Th}(s)}$
