Final answer:

The question lacks the necessary electron configuration to identify the correct element among Nitrogen (N), Oxygen (O), Neon (Ne), or Sodium (Na). Each element has a unique electron configuration, and without this information, we cannot determine the correct element.

Step-by-step explanation:

The question does not specify an electron configuration, so we cannot determine which element out of Nitrogen (N), Oxygen (O), Neon (Ne), or Sodium (Na) has the electron configuration in question. To identify the correct element, we would need the specific electron configuration provided. Each element has a unique electron configuration:

  • Nitrogen (N): The electron configuration is 1s²2s²2p³.
  • Oxygen (O): The electron configuration is 1s²2s²2p⁴.
  • Neon (Ne): The electron configuration is 1s²2s²2p⁶.
  • Sodium (Na): The electron configuration is 1s²2s²2p⁶3s¹.

In the case of sodium, the inner-shell configuration is the same as neon (Ne), thus the noble gas configuration for sodium is written as [Ne] 3s¹. Without knowing the specific configuration presented in the question, we cannot confidently select the correct element.
