(C) The borax bead test is used to identify transition metal ions. Borax $(Na_2B_4O_7 \cdot 10H_2O)$ on heating forms a transparent glassy bead consisting of sodium metaborate $(NaBO_2)$ and boric anhydride $(B_2O_3)$. These react with transition metal oxides to form colored metaborates. Since $Na$ is an alkali metal and not a transition metal,it does not form colored metaborates in the borax bead test. Therefore,$Sodium$ will not give a borax bead test.
