What is the general electronic configuration for the $2^{nd}$ row transition series?

Transition metals show paramagnetism.

The general electronic configuration of transition elements is

Assertion : Borax bead test is not suitable for $Al(III)$.
Reason : $Al_2O_3$ is insoluble in water.

Why do $CrO_3$ and $V_2O_5$ have low melting points?

Determine whether the following statements are True $(T)$ or False $(F)$:
$(a)$ Transition elements contain $d$-orbitals.
$(b)$ Ions of transition elements contain incompletely filled $d$-orbitals.
$(c)$ Only elements with completely filled $3d$ orbitals are considered transition elements.
$(d)$ Only elements that have incompletely filled $d$-orbitals in their ground state as well as in their ions are called transition elements.
