Properties of materials

The table below shows some physical and chemical properties of four elements, labelled A, B, C, and D.

Element	Melting point ( $∘C^\circ\text{C}$ )	Density ( $g/cm3\text{g/cm}^3$ )	Ions formed
A	98	0.97	$A+\text{A}^+$
B	-101	0.0032	$B−\text{B}^-$
C	1455	8.91	$C2+\text{C}^{2+}$ , $C3+\text{C}^{3+}$
D	842	1.54	$D2+\text{D}^{2+}$

Identify which element is a transition metal, justifying your choice using the properties in the table.
