Web1. Period 2 elements all have 2 outer shells, whereas period 3 elements all have 3 outer shells. 2. Period 3 had an extra electron shell than period 2, so the atomic radius is larger. 3. Boiling points in group 1 to 4 in both periods are fairly high, this is because group 1 to 4 have strong forces holding the structures together. 4. WebAcross period 2, the 2s sub-shell fills with two electrons, followed by the 2p sub-shell with six electrons.
