Question

multiple - choice question
what is the electronic configuration nitrogen?
1s¹2s¹2p⁵
1s²2s¹2p⁴
1s²2s²2p³
rewatch

Explanation:

Nitrogen has an atomic number of 7. The first energy level (n = 1) can hold a maximum of 2 electrons in the 1s orbital. The second energy level (n = 2) has the 2s orbital which can hold 2 electrons and the 2p orbital which can hold up to 6 electrons. For nitrogen with 7 electrons, the electron - filling order is 1s²2s²2p³.

Answer:

C. 1s²2s²2p³
