A) It shows magnetic property
B) It has variable valency
C) It has tendency for formation of coloured ions
D) It has complete d-orbitals
Correct Answer: D
Solution :
The d-block elements are those in which last electron enters into \[(n-1)d\]level. Their general electronic configuration is \[(n-1){{d}^{1-10}}n{{s}^{1-2}}.\] They have incompletely filled d orbital. Due to crystal field splitting d-block elements form coloured ions, show variable valency and magnetic property.
