Which of the following does not give Borax bead test?
Correct answer: D. Al
- A. Cu
- B. Cr
- C. NI
- D. Al
Explanation
Al: Aluminum, however, does not readily form colored complexes with borax under the conditions of the Borax bead test. While it might slightly modify the bead's transparency upon heating, it doesn't produce a distinct and easily identifiable color like the other metals mentioned.

About Transition Elements
Transition elements are identified by their partially filled d subshells in atoms or common ions. The topic covers the electronic structure of d-block elements, including the filling order of 4s and 3d orbitals, variable oxidation states and the distinction between transition elements and elements with completely filled d subshells.
