The utility of the rubidium–strontium isotope system results from the fact that 87 Rb (one of two naturally occurring isotopes of rubidium) decays to 87 Sr with a half-life of 49.23 billion years. Please give reasons to support your answer. Like other alkali metals, rubidium metal reacts violently with water. so francium would be more reactive than ... Barium reacts readily with water to form barium hydroxide, Ba(OH)2 and hydrogen gas (H2). Rubidium's main application is in the glass manufacturing. 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 it produces.
