This question is about the industrial extraction of transition metals.

A high-purity transition metal, $X\text{X}$ , is manufactured by the reduction of its anhydrous chloride with sodium metal at high temperatures in an inert argon atmosphere.

The balanced chemical equation for this extraction process is:

\text{XCl}_3 + 3\text{Na} \rightarrow \text{X} + 3\text{NaCl}

The total sum of the relative formula masses ( $M_r$ ) of the reactants in this balanced equation ( $XCl3+3Na\text{XCl}_3 + 3\text{Na}$ ) is $227.5$ .

Calculate the relative atomic mass ( $A_r$ ) of the metal $X\text{X}$ .

Relative atomic masses ( $A_r$ ): $Na=23.0\text{Na} = 23.0$ , $Cl=35.5\text{Cl} = 35.5$ .

Identify the transition metal $X\text{X}$ using the periodic table.
