Anomalous electron configurations
Some atoms, such as some transition metals and some elements in the lanthanide and actinide series, do not adhere strictly to Hund's rule and Pauli's pri
reason the anomalies are observed is the unusual stability of both half-filled and completely filled subshells. This behavior can be explained with an examp

than the combination of the filled 4s orbital and the partially filled 3d orbital. Thus; the observed electron configuration of the Cr aton is 1s² 2s² 2p® 3s²
Part D
Mo has an anomalous electron configuration. Write the observed electron configuration of Mo.
Express your answer in complete form in order of orbital filling. For example, 1s² 2s should be entered as 1s^225^2.
