Give reasons for the following :
(a) Transition metals form complex compounds.
(b) values for
are more negative than expected.
(c) Actinoids show wide range of oxidation states.
(a) It is because of smaller size of metal ions, high iconic charges and availability of vacant d-orbitals.
(b) It is because of extra stability of electronic configuration.
(c) It is because of less energy difference between 5s, 6d and 7d orbitals.
