The transition elements have a general electronic configuration:

Options

A. `ns^(2)np^(6)nd^(1-10)`
B. `(n-1)d^(1-10),ns^(0-2), np^(0-6)`
C. `(n-1)d^(1-10), ns^(1-2)`
D. `nd^(1-10)ns^(2)`

Answer

C

Explanation

In the transition elements, the d-orbitals are successively filled. The general electronic configuration of d-block is
`(n-1)d^(1-10)ns^(1-2)`
Where (n-1) stands for inner shell and d-orbitals may have one to ten electrons and the s-orbitals of the outermost shell (n) may have one or two electrons.
