The more the attraction, the more energy is needed to remove an electron from it's orbital and hence higher the IE. The other factors modify this main factor and thus change the expected IE values to the anomalous observed values.

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.
