"Change of a metal ion to a metal element" is not likely to indicate a double-displacement reaction. Double-displacement (metathesis) reactions exchange ions between compounds without changing oxidation states (examples: precipitation, gas formation, neutralization). Converting a metal ion to the elemental metal requires reduction (a redox/single-displacement process), not a metathesis.
