Answer:
No empty orbitals but five unpaired electrons.
Explanation:
Hello there!
In this case, when going over the empty orbitals in valence energy levels, it is required to develop the electron configuration in order to appropriately describe the element. In such a way, for the element whose atomic number is 25 because it equals the number of electrons, we obtain:
It means that the d orbital is half filled which means that it does not have any empty orbital wherein two electrons are contained per orbital. Moreover, we can find 5 unpaired electrons according to:
↑ ↑ ↑ ↑ ↑
Which is the orbital notation.
Best regards!
