Respuesta :

Here we have to choose the element which has 1s²2s²2p⁴ electronic configuration.

oxygen has the electronic configuration 1s²2s²2p⁴

The electronic configuration of the given elements are shown below:

nitrogen (N): 1s²2s²2p³

oxygen (O): 1s²2s²2p⁴

phosphorous (P): 1s²2s²2p⁶3s²3p³

Sulfur (S): 1s²2s²2p⁶3s²3p⁴

Thus oxygen has the electronic configuration 1s²2s²2p⁴
