Question

Choose the statements suitable for d block elements

a. They form coloured compounds.

b. Largest atoms in the period

c. Show different Oxidation State

d. They are non metals.​

Answer 1

Explanation:

Option A

The reason why transition metal (d-block elements) in particular are colorful is because they have unfilled or either half filled d orbitals. There is Crystal field theory which explains the splitting of the d orbital, which splits the d orbital to a higher and lower orbital. Now, the electrons of the transition metal can "jump".
