Transcript text: Fill in the information missing from this table: \begin{tabular}{|c|c|} \hline \multicolumn{2}{|c|}{ Some electron shells } \\ \hline shell & subshells \\ \hline 2 & $2 s, 2 p$ \\ \hline 3 & $\square$ \\ \hline 4 & $\square$ \\ \hline \end{tabular}

Solution

Solution Steps

Step 1: Understanding Electron Shells and Subshells

Electron shells are labeled by principal quantum numbers (n = 1, 2, 3, ...). Each shell can contain one or more subshells, which are labeled by the azimuthal quantum number (l = 0, 1, 2, ...). The subshells are denoted by letters: s (l = 0), p (l = 1), d (l = 2), and f (l = 3).

Step 2: Identifying Subshells for Shell 3

For shell 3 (n = 3), the possible values of l are 0, 1, and 2. Therefore, the subshells for shell 3 are:

3s (l = 0)
3p (l = 1)
3d (l = 2)

Step 3: Identifying Subshells for Shell 4

For shell 4 (n = 4), the possible values of l are 0, 1, 2, and 3. Therefore, the subshells for shell 4 are:

4s (l = 0)
4p (l = 1)
4d (l = 2)
4f (l = 3)

Final Answer

\[ \begin{array}{|c|c|} \hline \multicolumn{2}{|c|}{\text{Some electron shells}} \\ \hline \text{shell} & \text{subshells} \\ \hline 2 & 2s, 2p \\ \hline 3 & \boxed{3s, 3p, 3d} \\ \hline 4 & \boxed{4s, 4p, 4d, 4f} \\ \hline \end{array} \]
