Certainly! Here is the detailed, step-by-step solution for each element's chemical formula in its standard state, including the physical state symbol.
1. Iron (Fe) in its standard state:
- The chemical symbol for iron is Fe.
- In its standard state, iron is a solid.
- Therefore, the complete chemical formula is [tex]\( \text{Fe (s)} \)[/tex].
2. Nitrogen (N[tex]\(_2\)[/tex]) in its standard state:
- The chemical symbol for nitrogen is N.
- Nitrogen naturally exists as a diatomic molecule, meaning two nitrogen atoms are bonded together.
- In its standard state, nitrogen is a gas.
- Therefore, the complete chemical formula is [tex]\( \text{N}_2 \text{ (g)} \)[/tex].
3. Thorium (Th) in its standard state:
- The chemical symbol for thorium is Th.
- In its standard state, thorium is a solid.
- Therefore, the complete chemical formula is [tex]\( \text{Th (s)} \)[/tex].
4. Sodium (Na) in its standard state:
- The chemical symbol for sodium is Na.
- In its standard state, sodium is a solid.
- Therefore, the complete chemical formula is [tex]\( \text{Na (s)} \)[/tex].
Now let's complete the table with the correct formulas:
[tex]\[
\begin{array}{|c|c|}
\hline \text{element} & \text{formula} \\
\hline \text{iron} & \text{Fe (s)} \\
\hline \text{nitrogen} & \text{N}_2 \text{ (g)} \\
\hline \text{thorium} & \text{Th (s)} \\
\hline \text{sodium} & \text{Na (s)} \\
\hline
\end{array}
