Vedclass · Answer

(C) The transition elements are defined as elements having partially filled $d$-orbitals in their ground state or in any of their oxidation states.There are approximately $60$ transition elements out of the total known elements.Percentage of transition elements $= (	ext{Number of transition elements} / 	ext{Total number of elements}) 	imes 100$.Taking the total number of elements as approximately $105$ and the number of transition elements as $61$,the calculation is $(61 / 105) 	imes 100 \approx 58.1\%$,which is approximately $60\%$.

$I. \ Zn^{2+}$	$(i) \ d^8 \ \text{configuration}$
$II. \ Cu^{2+}$	$(ii) \ \text{Colourless}$
$III. \ Ni^{2+}$	$(iii) \ \mu = 1.73 \ \text{BM}$

Approximately what percentage $(\%)$ of the total elements are transition elements?
