This is due to the increase in nuclear charge having a greater pull on the electrons and therefore … WebAcross period 2, the 2s sub-shell fills with two electrons, followed by the 2p sub-shell with six electrons. Across period 3, the same pattern of filling is repeated for the 3s and 3p sub-shells, For each period, the s and p sub-shells are filled in the same way - a periodic pattern.
