An element ‘X’ belongs to the fourth period and fifteenth group of the Periodic Table. Which one of — Periodic Table and Periodicity Chemistry Question

💡 Solution & Explanation

Given, element X belongs to the fourth period and fifteenth group, thus the outermost shell of element X is 4 and the number of outermost electrons present is 5. PERIODIC PROPERTIES 34 Thus, the electronic configuration of element X will be 2 2 6 2 6 2 10 3 1s 2s 2p 3s 3p 4s 3d 4p . Therefore, it has completely filled ‘s’ orbital and half-filled ‘p’ orbitals.
