Chemistry Help Mo has an anomalous electron configuration. Write the observed electron configuration of Mo.?
I already tried 1s^22s^22p^63s^23p^63d^104s^24p^64d^55s^1
and
1s^22s^22p^63s^23p^63d^104s^24p^64d^45s^2
but they were incorrect. Any thoughts?
Surprisingly, electron configurations contain spacing and punctuation. Spaces go between the types of orbitals and commas go between the energy levels.
Mo….. 1s2, 2s2 2p6, 3s2 3p6 3d10, 4s2 4p6 4d5, 5s1
It follows the same trend that chromium does which is just above it in the first row of transition metals. Also, unlike what some instructors would have you believe, the 5s is higher in energy than the 4d and is occupied last, and is written last. Electrons are lost from the energy level with the highest energy first which is why there are no ions of Mo with electrons in the 5s.
Mo has an anomalous electron configuration. write the observed electron configuration of mo.
