Question

The outside energy levels of an atom have the configuration $s^2{p}^6{d}^5{s}^2$. The atom belongs to ______________.

• A. Copper family
• B. Zinc family
• C. Iron family
• D. Manganese family

Answer 1

The correct option is D Manganese family

The element has electronic configuration $s^2{p}^6{d}^5{s}^2$. i.e. the number of valance electrons $=7$. Thus, it belongs to the manganese $\left(\right[Ar\left]3d^{5}4s^2\right)$family.
