THE d-AND f-BLOCK ELEMENTS

16173 The catalytic activity of the transition metals and their compounds is ascribed to their

1 Chemical reactivity
2 Magnetic behaviour
3 Unfilled \(d-\) orbitals
4 Ability to adopt multiple oxidation states and their complexing ability
THE d-AND f-BLOCK ELEMENTS

16174 What is the general electronic configuration for \(2^{nd}\) row transition series

1 \([Ne]3{d^{1 - 10}},4{s^2}\)
2 \([Ar]3{d^{1 - 10}},4{s^{1 - 2}}\)
3 \([Kr]4{d^{1 - 10}},\,\,5{s^{1 - 2}}\)
4 \([Xe]5{d^{1 - 10}},\,\,5{s^{1 - 2}}\)
THE d-AND f-BLOCK ELEMENTS

16175 Transitional elements are named transition elements because their characters are

1 In between \( s\) and \( p -\)  block elements
2 Like that of \(p \) and \(d -\) block elements
3 They are members of \(I -A\)  group
4 They are like inactive elements
THE d-AND f-BLOCK ELEMENTS

16176 Those elements whose two outermost orbitals are incompletely filled with electrons are

1 \(p -\) block elements
2 \(s -\) block elements
3 Transitional elements
4 Both \( s\) and \(p -\)  block elements
