Question :-

Write the Electronic Configuration Of Chromium.

Answer :-

As we know that, Atomic number of Chromium is 24.So, the expected electronic configuration should have been as follows:-

$\sf\pink{:\implies} \pink{ Cr_{24} : 1s²\: 2s² \: 2p⁶\: 3s²\: 3p⁶\: 4s²\: 3d⁴}$⛌

• We can also expect it as follows:-

$\sf\pink{:\implies} \pink {Cr_{24} : [Ar] \:4s² \:3d⁴ }$⛌

• But we don't get the above electronic arrangement because when the "d" orbital becomes half filled with electrons (d⁵ condition), the atom gains stability.
• That's why 1 electron from 4s orbital goes to 3d to make 3d⁵ configuration.Hence, the actual configuration is as follows:-

$\sf\red{:\implies } \red {Cr_{24} : 1s² \:2s²\: 2p⁶ \:3s² 3p⁶ \:4s¹ \:3d⁵}$☑
