Final answer:
The partial electron configuration 1s²2s²2p⁶x represents the electron configuration in the 2p orbital of the atom with 11 electrons. In this case, x represents the 3p¹ orbital.
Step-by-step explanation:
The partial electron configuration 1s²2s²2p⁶x represents the electron configuration in the 2p orbital of the atom with 11 electrons. To determine the value of x, we can subtract the total number of electrons in the filled orbitals (1s²2s²2p⁶) from the total number of electrons in the atom (11). Therefore, x = 11 - (2 + 2 + 6) = 1. So, x represents the 3p¹ orbital. The correct option is C) 3p¹.
