Question

The property which is not characteristic of transistion metals is
(a) variable oxidation states.
(b) tendency to form complexes.
(c) formation of coloured compounds.
(d) natural radioactivity.

Answer 1

The answer would be (d).

Transition metals (d-block elements) don't show radioactivity in general.. while these are characterised to show variable oxidation states, form complexes and coloured compounds..

Hope it helps ya:)

Answer 2

Answer:

(d) natural radioactivity.

Explanation:

The miracle of robotic and nonstop and willful decomposition of an unstable nexus accompanied by the emigration of active radiations is called natural radioactivity. The substance which exhibits radioactivity is called a radioactive substance.e.g. Uranium, thorium, radium,etc.

Transition essence( d- block rudiments) do not show radioactivity in general. while these are characterised to show variable oxidation countries, form complexes and coloured composites.
