Question

The atomic number$\left(z\right)$ of an element is 24. In its ground state how many electrons are present in the ${}^{\prime }{N}^{\prime }$ shell?

• A. 4
• B. 2
• C. 1
• D. 3

Answer 1

The correct option is C 1

If atomic number is 24 so element is chromium and configuration is $\left[Ar\right]3d^{5}4s^1$ and $N$ shell means $n=4$.

According to configuration in 4th orbit or shell only 1 electron are present.
