Identify the metal that froms colourless compounds.

A

Iron(Z=26)

B

Chromium (Z=24)

C

Vanadium (Z=23)

D

Scandium(Z=21)

Text Solution

Verified by Experts

The correct Answer is:
D
d-block elements show `+3` as the common oxidation state. For scandium (Z=21), electronic configuration is `d^(1)s^(2)`. After the remove of `3+` electrons `(Sc^(3+))`,it acquires a stable configuration `(d^(0))`.
Hence, it froms colourless compounds.
