12 Questions
What is the general electronic configuration for d-block elements?
(n-1)d1-10 ns1-2
Which elements are known as lanthanoids?
Cerium (58) to Lutetium (71)
What is defined as a transition element?
An element with incompletely filled d-orbitals
Why are zinc, cadmium, and mercury not regarded as transition metals?
Due to completely filled d-orbitals
Which elements are known as actinoids?
Thorium (90) to Lawrencium (103)
Which series of transition elements consists of the atomic numbers 21 to 30?
3d-transition series
Why do transition elements have strong metallic bonds?
Thanks to the presence of unpaired electrons
What causes the atomic radii of Cu and Zn to be bigger compared to Fe, Co, and Ni?
Increase in shielding effect and electron-electron repulsion
What leads to the irregular variation in ionization energies of transition metals?
Lanthanoid Contraction effect
Why does the ionization energy of the 5d transition series differ from the 3d and 4d transition series?
Because of the Lanthanoid Contraction
What property makes transition metals suitable for use as catalysts?
(n-1)d as well as ns electrons taking part in bond formation
Why are most transition metals paramagnetic in nature?
Increase in the number of unpaired electrons
