The trends in electron configuration on the periodic table is as follows.

1. The number of valence electrons from left to right across the period increases across the period.

2. The number of valence electrons from top to bottom of the group on the periodic table remains thesame (because elements in the same group has thesame number of valence electrons in their outermost shell).

3. Electrons in the outermost shell in elements 1 and 2 on the periodic table(hydrogen and helium) are always in the s-orbital.

4. Electrons in the outermost shell in elements 3 to 12 on the periodic table (lithium, berilium, boron, carbon, nitrogen, oxygen, chlorine, neon, sodium and magnesium) are always in the s and p orbitals.

5. Electrons in the outermost shell in elements 13 to 18 on the periodic table (aluminum, silicon, Phosphorus, sulphur, florine and argon) are always in the p-orbital.
