Each rubidium halide crystallizing
WebRubidium is a soft, ductile, silvery-white metal that melts at 39.3 oC. One of the alkali metals, it is positioned in group 1 (or IA) of the periodic table between potassium and cesium. Naturally occurring rubidium is slightly radioactive. Rubidium is an extremely reactive metal—it ignites spontaneously in the presence of air WebFeb 21, 2024 · Moisten the wire with water. Dip the wire into the solid you're testing, making sue that a sample sticks to the wire. Place the wire in the flame and observe any change in the flame color. The colors observed during the flame test result from the excitement of the electrons caused by the increased temperature.
