Question: how many valence electrons in p orbital?
Answer: Fill the orbitals of the atom in the order 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p and 5s. Each s orbital can hold two electrons, each p orbital can hold six electrons and each d orbital can hold 10 electrons. Discern which s or p orbital filled last. These orbitals contain the valence electrons for the element.
