$Sc\, (Z = 21)$ is a transition element but $Zn\, (Z = 30)$ is not because
both $Sc^{3+}$ and $Zn^{2+}$ ions are colourless and form white compounds.
in case of $Sc, 3d$ orbitals are partially filled but in $Zn$ these are filled.
last electron is assumed to be added to $4s$ level in case of $Zn.$
both $Sc$ and $Zn$ do not exhibit variable oxidation states.
Which of the following transition metal is present in misch metal
Discuss the magnetic properties of transition elements.
If $CdI_2$ is pink in colour, the $CdCl_2$ will be ........... coloured.
While filling up of electrons in the atomic orbitals, the $4 s$ orbital is filled before the $3 d$ orbital but reverse happens during the ionisation of the atom. Explain why?
The transition metals mostly are
