An element can easily have more than 4 shells.. E.g. all elements in the 7th period have 7 shells, wherein their electrons are distributed in 4 types of orbitals, being: s, p, d and f orbitals.
Two electrons imply that the element is in the second period. The 4 valence electrons says that it is located in group 4A (or group 14 in modern notation). Hence, this element is carbon.The element has 2 electron shells means the element is in the 2nd group. This element is carbon. It has 4 valence electrons.
There are 4 electronic shells in period 4 while there are 5 shells in period 5.Elements of period 4 are smaller in size as compared to elements of period 5.Example of period 4 element is potassium and period 5 element is tin.

if an element has 1 shell in its atom it is in period 1and so on... 2 shells=period 2 3 shells=period 3 4 shells=period 4 5 shells=period 5 6 shells=period 6 7 shells=period 7
