Fun Facts About Francium
• There is less than only 30 grams of francium in the entire Earth’s crust.
• Properties are very similar to those of cesium.
• Most reactive alkali metal in group one.
• Has a half-life of 22 minutes• Very radioactive metal.• Within 22 minutes it quickly decays
into other elements.• Longest-lived isotope. Brennan Bedford 5-1
