Question

Please explain what are transition and inner-transition elements​

Answer 1

Answer:

Transition metals are in the d-block and have valence electrons in the d-orbital's. They can form multiple oxidation states and form different ions. Iron, Cobalt and Nickel are ferromagnetic. Inner transition metals are in the f-block and have valence electrons in the f-orbital's.

Answer 2

The transition elements are in the d-block, and in the d-orbital have valence electrons. They can form several states of oxidation and contain different ions. Inner transition elements are in the f-block, and in the f-orbital have valence electrons. They are the Lanthanides, and the Actinides.☺
