Higher melting point rubidium
Rubidium is a very soft, ductile, silvery-white metal. It is the second most electropositive of the stable alkali metals and melts at a temperature of 39.3 °C (102.7 °F). Like other alkali metals, rubidium metal reacts violently with water. As with potassium (which is slightly less reactive) and caesium (which is slightly more reactive), this reaction is usually vigorous enough to ignite the hydrogen gas … WebAs you can see, tungsten is #1 with an astonishing 3380°C melting point.

It is a cubic crystal with rock-salt structure. There are several methods for synthesising rubidium fluoride. One involves reacting rubidium hydroxide with hydrofluoric acid: RbOH + HF → RbF + H 2 O. Another method is to neutralize rubidium carbonate with hydrofluoric acid:
WebRubidium has a higher mass number than potassium, so it is likely that potassium is less dense than rubidium. Therefore, option (B) is a true statement. However, we are looking for the incorrect statement. So option (B) cannot be the answer to this question. Cesium has a higher mass number than lithium.
