Answer» Inert gas elements : (2, 8, 8), (2, 8). Third row elements : (2, 8, 2), (2, 8, 7), (2, 8, 8). Second group elements : (2, 8, 2), (2, 2). Seventeen group elements : (2, 7), (2, 8, 7). [Note: (1) The outermost shell of all noble gases contain 8 electrons (except He). (2) Atoms or all 3rd row elements contain 3 shells. Out of which first shell contains 2 and 2nd shell contains 8 electrons. (3) The elements of group 17 contains 7 electrons in the outermost shell. (4) The elements or group 2 contains 2 electrons in the outermost shell.] |
