Question

transition elements have similar properties explain why , in terms of electronic structure?

Answer 1

Answer:

All transition elements exhibit similar properties because of the identical electronic configuration of their peripheral shell. This happens as each additional electron enters the penultimate 3d shell. This creates an effective shield between the nucleus and the outer 4s shell.

Explanation:

General Properties

All transition elements exhibit similar properties because of the identical electronic configuration of their peripheral shell. This happens as each additional electron enters the penultimate 3d shell. This creates an effective shield between the nucleus and the outer 4s shell. The peripheral shell configuration of these elements is ns2. The general properties of the transition elements are as follows:

form stable complexes

Have high melting and boiling points

Contain large charge/radius ratio

Form compounds which are often paramagnetic

Are hard and possess high densities

Form compounds with profound catalytic activity

Show variable oxidation states

form coloured ions and compounds.
