Explanation:
Electronic Configurations:
The maximum number of electrons in the dxy orbital is 2. To determine which of the given species has the maximum number of electrons in the dxy orbital, we need to look at their electronic configurations.
Electronic Configurations:
a) Cr: [Ar] 3d5 4s1
b) Fe3+: [Ar] 3d5
c) Cu: [Ar] 3d10 4s1
From the electronic configurations, we can see that:
- Cromium (Cr) has 5 electrons in the d orbital (d1, d2, d3, d4, d5)
- Iron (Fe3+) has 5 electrons in the d orbital (d1, d2, d3, d4, d5)
- Copper (Cu) has 10 electrons in the d orbital (d1, d2, d3, d4, d5, d6, d7, d8, d9, d10)
Therefore, the species with the maximum number of electrons in the dxy orbital is Copper (Cu) because the dxy orbital is one of the five d orbitals, and copper has a completely filled d orbital with 10 electrons.
Hence, the correct answer is option 'C'.

Talking about valence electrons,
Cr(Z=24) : 4s¹3d⁵
Fe(Z=26) => Fe +3(Z=23) :4s²3d³
Cu(Z=29) => Cu+(Z=28) : 4s²3d⁸
As we clearly see that maximum electrons are filled in Cu+ .
Therefore the correct option is (c)
Cr(Z=24) : 4s¹3d⁵
Fe(Z=26) => Fe +3(Z=23) :4s²3d³
Cu(Z=29) => Cu+(Z=28) : 4s²3d⁸
As we clearly see that maximum electrons are filled in Cu+ .
Therefore the correct option is (c)
