D:
Correct Answer
D
Explanation
The electron configuration 1s² 2s² 2p³ corresponds to the nitrogen (N) atom. Let me break down the electron configuration for you:
- 1s²: This represents two electrons in the 1s orbital.
- 2s²: This represents two electrons in the 2s orbital.
- 2p³: This represents three electrons in the 2p orbitals.
Adding them up, you have a total of 2 + 2 + 3 = 7 electrons. The atomic number of nitrogen is 7, indicating that it has 7 electrons. Therefore, the element with this electron configuration is nitrogen (N).
