Final answer:

The element with electron configuration [Kr] 5s24d105p2 is tin (Sn), which is a representative metal in the p-block and belongs to group 14 of the periodic table.The answer is a)

Step-by-step explanation:

An element with the electron configuration [Kr] 5s24d105p2 is a representative element in the p-block of the periodic table, specifically a metal. Since the electron configuration ends with 'p2', it indicates that the last electrons added are in a p orbital. Given the complete d orbital (4d10) in an energy level less than the p orbital being filled, this element belongs to the main group metals rather than transition metals.

The representative metals typically display metallic character, which includes the ability to lose valence electrons and possession of high thermal and electrical conductivity. According to the provided information, the element with the electron configuration [Kr] 5s24d105p2 corresponds to the element tin (Sn) which is found in group 14 of the periodic table.
