Write an electron configuration for each element and the corresponding Lewis structure. Indicate which electrons in the electron configuration are included in the Lewis structure.
Lithium : The electronic configuration of Li = 1s22s1.
The electron present in outer most orbital that is valence electron present in 2s1 is involved in the bond formation .
Phosphorous : The electronic configuration of P = 1s22s22p63s23p3.
The 3 electrons present in the valence P orbital will be involved in the bond formation .
