Identify the atom whose electron configuration is [Ar]4s^23d^6. write the one or two letter symbol for the element. How many unpaired electrons are there in the ground state of this atom?

Solutions

Expert Solution

Total number of electrons in system [Ar]4s² 3d⁶

= [18] + 2 + 6 = 26

This atomic number belongs to Iron = [Fe]

Number of unpaired electrons in [Fe] in the ground state = 4, as number of electrons in 3d orbitals = 6
