, 12.1a TRANSITION ELEMENTS
Often referred as d-block elements
Definition: element which forms one or
more stable ions with incompletely filled
d orbitals
Scandium and zinc are excluded from
this definition as the most stable ion for
both are +3 and +2 respectively – only
one ion is formed
Sc3+: [Ar] 3d0 – empty d orbital
Zn2+: [Ar] 3d10 – complete d orbital
