Question

Five ionization energy values in $kJ / mol$ are listed below: $E_{1}=870, E_{2}=830, E_{3}=1010, E_{4}=1290, E_{5}=376$ These are

• A. Successive ionization energies for the element with atomic number $ 5$
• B. The first $I.E.$ of successive elements in group $15,16 , 17,18$ and $1 $ respectively
• C. The first $I.E.$of elements with atomic number $1$ to $5$
• D. Successive $ I.E$. for transition elements with four electrons in $d-$subshell

Answer 1

Answer: (D)

Correct answer is (d) Successive $ I.E$. for transition elements with four electrons in $d-$subshell
