Question

Electronic configuration of copper sulphate ( with the help of atomic number)​

Answer 1

The Electronic Configuration of Copper Sulphate is 3d10 4s1.

The atomic number of Copper is 29.

Thus it will contain 29 electrons in it’s atom.

So it’s configuration will be

[Ar] 4s1 3d10.

Here one electron from the 4s2 jumps to the 3d9 orbital because the fully filled subshell os more stable due to increase in exchange energy.

Now, Cu2+ means loss of two electrons,

So 1 electron will be removed from 4s subshell and 1 electron from 3d subshell.

Thus the configuration will be

[Ar] 3d9.



Hope this Helps you❤️
