\begin{tabular}{ccc} Element & Full Configuration \\ \hline \( 5 . \mathrm{Ne} \) & \( \square \)\end{tabular}

To fill in the full electron configuration for the element with atomic number 5, which is boron (B), we can start by writing the electron configuration based on the order of filling the atomic orbitals. The electron configuration for boron (atomic number 5) is: 1. The first two electrons fill the 1s orbital: \( 1s^2 \) 2. The next three electrons go into the 2s and 2p orbitals: \( 2s^2 2p^1 \) Putting it all together, the full electron configuration for boron is: \[ 1s^2 2s^2 2p^1 \] So, the completed table would look like this: \[ \begin{tabular}{ccc} Element & Full Configuration \\ \hline \( 5 . \mathrm{Ne} \) & \( 1s^2 2s^2 2p^1 \) \end{tabular} \]
