Question

For $O_2$ and $N_2$ write electronic configuration.

Answer 1

According to molecular orbital theory,

electronic configuration of $O_2$ is ($\sigma 1s^2$ $\sigma \ast 1s^2$ $\sigma 2s^2$ $\sigma \ast 2s^2$ $\sigma 2p_z^2$ $\pi 2p_x^2$ $\pi 2p_y^2$ $\pi \ast 2p_x^1$ $\pi 2p_y^1$)

Electronic configuration of $N_2$ is ($\sigma 1s^2$ $\sigma \ast 1s^2$ $\sigma 2s^2$ $\sigma \ast 2s^2$ $\pi 2p_x^2$ $\pi 2p_y^2$ $\sigma 2p_z^2$)
