The element with the electron configuration of \(4s^2 4p^3\) is Arsenic (As), which has an atomic number of 33.
The full electron configuration for Arsenic is:
\[
1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 4p^3
\]
To count the number of inner (core) electrons, we can consider all electrons that are not in the outermost shell, which consists of the 4s and 4p electrons.
The inner electrons, therefore, include:
- \(1s^2\): 2 electrons
- \(2s^2\): 2 electrons
- \(2p^6\): 6 electrons
- \(3s^2\): 2 electrons
- \(3p^6\): 6 electrons
Adding these together:
\[
2 + 2 + 6 + 2 + 6 = 18 \text{ inner electrons}
\]
Thus, the number of inner electrons in Arsenic is 18.
