- why do you not need to specify the molecular shap for an atom with 1 electron grouparrow_forwardIn reference to the following figure, which of the following statements is not true? a. The bond in the hydrogen molecule is formed by the overlap of 1s atomic orbitals. b. The overlap of electron waves represented by the atomic orbitals may result in constructive (in-phase) or destructive (out-of-phase) interference. c. In-phase overlap between two 1s orbitals results in a new orbital having higher energy than either of the s orbitals. This new orbital concentrates the electron probability between the two nuclei. d. Out-of-phase overlap between two 1s orbitals results in a new orbital having higher energy than either of the s orbitals. This new orbital places most of the electron probability to the left and right of the two nuclei. e.
