Final answer:
Sulfur (S) is from a representative group on the periodic table, specifically group 16 which is part of the p block, unlike Mn, Co, and V which are transition elements.
Step-by-step explanation:
Among the elements provided (Mn, Co, V, S), sulfur (S) is from a representative group. Representative elements are those where the s and p orbitals are filling. Sulfur comes under group 16, which is part of the p block and therefore a representative element. On the other hand, manganese (Mn), cobalt (Co), and vanadium (V) are transition elements where the d orbitals are filling. This categorization is key in understanding the periodicity and properties of the elements on the periodic table.
