Question

Illustrate the exception to the electron configuration of molybdenum.

Accepted Answer

here, it says illustrate the exception to the electron configuration of molybdenum. Molybdenum is M. O. It has an atomic number off 42. So it has 42 electrons. If you were to look at the periodic table, we're gonna write down what we see. Initially, what we see here is crypt on five s to, and then we see four d four. Mulet Denham is right below chromium. And remember, we said that in that column. Both chromium and molybdenum are exceptions to our typical electron configuration. Here, it's a D four element. Remember, D is most stable when it's half filled. To do that, we're gonna take one electron from the S orbital and promoted up to a D orbital. In that way make a half filled set of the orbital's. So the correct electron configuration from a lived in them is actually crypt on five s. One four d five. So now we're gonna illustrate that here with this electron orbital diagram. So here, this would be quipped on this is for us because remember, woman five s, because remember, as sub level has one orbital and then these five would be our four D set of Orbital's. So we have only one here in the five s orbital and then we have five here in 40. Following hunts rule. It would be up, up, up, up and up. So this would be the correct illustration for the electron over the diagram for Millennium Mulet, Denham, Adam.
