- 7.21 Theoretical models for the structure of atomic nuclei predict the existence of superheavy elements that have not yet been discovered and suggest that such elements might be fairly stable if they could be produced. So researchers are currently trying to synthesize these superheavy elements to test these theories. Element 117 has been synthesized and named Tennessine (Ts). What would the Lewis dot symbol be for this new element?Identify the element that corresponds to each of the simplified photoelectron spectral data given below. (Energy data taken from D. A.
