Question

the electron configuration of nitrogen (n) is
1s²2s²2p³
1s²2s²2p⁴
1s²2s²2p⁵
1s²2s²2p⁶

Explanation:

Nitrogen has an atomic number of 7. Electrons fill orbitals in the order of 1s, 2s, 2p. The 1s orbital can hold 2 electrons, the 2s orbital can hold 2 electrons and the 2p orbital can hold up to 6 electrons. For nitrogen with 7 electrons, the electron - configuration is 1s²2s²2p³.

Answer:

1s²2s²2p³
