Question

The discovery of two new elements (atomic numbers 113 and 115) was announced in February 2004. Use spd f and noble gas notations to give the electron configurations of these two elements. (Express your answer as a series of orbitals. For example, the electron configuration of Li would be entered in complete forma s 1s^2 2s^or in condensed form as [He]2s^1. spd f notation configuration for the element 113: Noble gas notation configuration for the element 113: spd f notation configuration for the element 115: Noble gas notation configuration for the element 115: For each of these elements, name another element in the same periodic group. Another element for the element 113 is .
