Question

1. Explain the anomalous behavior of copper and chromium.
​

Answer 1

$\huge\tt\red{Answer!}$

.In Cr we can see that last d orbital is having 4 electrons in outermost shell to to attain stability it should have at least 5 electrons in its d subshell so it will take 1 electron from s subshell and now Cr will be more stable in its new electronic configuration. Hence, Cr and Cu are called exceptional configuration.
