Q.
The element with the electronic configuration as $\lbrack Ar\rbrack 3d^{10}4s^{2}4p^{3}$ represents a
A) Metal
B) Non-metal
C) Metalloid
D) Transition element
Explanation
(c)
Electronic configuration reveals that the p-orbital of the element is not complete. Therefore, it is a p-block element. Moreover, the atomic number of the element is 33(As). Therefore, it is a metalloid.
