Transition metal definition
$partly filled d -orbitals in element or ion$
Q1MCQTransition metal
A transition element has:
- A
  partly filled $d$-orbitals
- B
  a filled $d$-orbital
- C
  only $s$-electrons
- D
  no $d$-electrons
General configuration
$(n - 1) d^{1 - 10} n s^{0 - 2}$
Q1MCQConfiguration
The general configuration of $d$-block elements is:
- A
  $(n-1)d^{1-10}ns^{0-2}$
- B
  $ns^{2}np^{6}$
- C
  $ns^{1}$
- D
  $nf^{1-14}$
Variable oxidation states
$due to close (n - 1) d and n s energies$
Q1MCQVariable OS
Transition metals show variable oxidation states because:
- A
  $(n-1)d$ and $ns$ energies are close
- B
  they are gases
- C
  they have no $d$-electrons
- D
  they are radioactive
Spin-only magnetic moment
$μ = n (n + 2) BM$
Coloured ions
$due to d - d transitions$
Q1MCQColour
Transition-metal ions are coloured due to:
- A
  $d$–$d$ transitions
- B
  nuclear decay
- C
  $s$–$p$ transitions
- D
  vibrations
Catalytic property
$variable oxidation states / surface adsorption$
Q1MCQCatalysis
Transition metals are good catalysts because of:
- A
  variable oxidation states
- B
  low density
- C
  gaseous state
- D
  radioactivity
Formation of complexes
$small size, high charge, vacant d -orbitals$
Q1MCQComplexes
Transition metals form complexes because they have:
- A
  vacant $d$-orbitals and high charge/size ratio
- B
  large size
- C
  low charge
- D
  full octet
Interstitial compounds
$small atoms (H,C,N) occupy interstices$
Q1MCQInterstitial
Interstitial compounds form when small atoms like $H, C, N$:
- A
  occupy the interstices of the metal lattice
- B
  replace metal atoms
- C
  form ionic bonds
- D
  evaporate
Alloy formation
$similar atomic sizes$
Q1MCQAlloys
Transition metals readily form alloys because of their:
- A
  similar atomic sizes
- B
  different charges
- C
  gaseous nature
- D
  low melting points
Lanthanide contraction
$decrease in size across the 4f series$
Q1MCQLanthanide contraction
The lanthanide contraction affects the size of:
- A
  the elements after the 4f series
- B
  only lanthanides
- C
  $s$-block metals
- D
  noble gases
KMnO4 oxidation state
$Mn is + 7$
K2Cr2O7 oxidation state
$Cr is + 6$
Zn, Cd, Hg
$not typical transition metals (full d^{10})$
Q1MCQZn Cd Hg
Zn, Cd and Hg are not typical transition metals because they have:
- A
  a completely filled $d^{10}$ configuration
- B
  no electrons
- C
  partly filled $d$
- D
  $f$-electrons
Highest oxidation state (Mn)
$+ 7$
