Question

What is the electron configuration [Kr] 4d⁷ 5s¹?
Options
A A representative element in the p-block
B A transition element in the d-block
Correct Answer
C An inner transition element in the f-block
D A noble gas
Correct Answer

Option B is the correct answer.

Detailed Explanation

The configuration [Kr] 4d⁷ 5s¹ shows electrons entering the d subshell (4d). Elements with partially filled d subshells (or that can form ions with partially filled d subshells) are classified as transition elements (d-block elements).

Hint

Transition elements involve the filling of d orbitals.
