D Block Flashcards
Metals that have incomplete d subshell.
Transition metals
Transition metals are found in ____?
D block
Which of the elements of d block are not regarded as transition elements ?
Zinc (Zn)
Cadmium (Cd)
Mercury (Hg)
Coppernicium (Cn)
Why are elements of group 12 not regarded as transition elements?
Completely filled orbitals in ground state and oxidation state.
D orbitals are more influenced by surroundings as well as affect atoms and molecules around them. Why ?
D orbitals protrude to the periphery of atom more than s and p orbitals.
What properties do transition metals and their compounds exhibit ?
Catalytic properties and
Paramagnetic behavior
Silver has fully filled d orbital in ground state. However, it is not a transition metal. Why ?
Silver belongs to group 11.

All d block elements except
Zinc (Zn)
Cadmium (Cd)
Mercury (Hg)
Manganese (Mn)
What kind of physical properties do transition elements display ?
Typical metallic properties like ductility, malleability, high thermal conductivity, high tensile strength, metallic lustre etc.
