Final answer:
The correct electron configuration amongst the options provided is 1s²2s²2p⁶63s¹, which follows the principles for electronic arrangements in atoms.
So, the correct answer is C.
Step-by-step explanation:
The question asks which electron configuration is correct. Out of the options provided, the correct electron configuration is:
This configuration follows the correct order of rising energy levels and fills the orbitals according to the Aufbau principle, Pauli exclusion principle, and Hund's rule. The other options either do not follow the correct order of orbital filling (option b) or have incorrect numbers of electrons in orbitals (options a and d).
So, the correct answer is C.
