To label the parts of the electron configuration $$ 2p^2 $$, we can break it down into its components:

1. **Principal Quantum Number (n)**: This indicates the energy level of the electron. In this case, the principal quantum number is $$ 2 $$.

2. **Subshell Type (l)**: This indicates the type of subshell. The letter $$ p $$ corresponds to the angular momentum quantum number $$ l = 1 $$.

3. **Number of Electrons (e)**: The superscript $$ 2 $$ indicates the number of electrons in that subshell. Here, it means there are 2 electrons in the $$ 2p $$ subshell.

Now, we can label the parts as follows:

- The number $$ 2 $$ represents the principal quantum number $$ n $$.
- The letter $$ p $$ represents the subshell type.
- The superscript $$ 2 $$ represents the number of electrons in that subshell.

Thus, the labeled parts of the electron configuration $$ 2p^2 $$ are:

- **Principal Quantum Number (n)**: $$ 2 $$
- **Subshell Type (l)**: $$ p $$
- **Number of Electrons (e)**: $$ 2 $$
The electron configuration $$ 2p^2 $$ has: - Principal Quantum Number (n): 2 - Subshell Type (l): p - Number of Electrons (e): 2

\( \left. \begin{array} { | l l | } \hline \text { REVIEW: Label the e-configuration parts: } \\ { 2 p ^ { 2 } } & { 2 } \\ { 2 : } & { p } \\ \hline \end{array} \right. \)
