All about Francium: Properties, Color, Uses and more... 2022

Welcome to my Francium element data sheet page.

On this page I'll provide comprehensive data for Francium. I hope you profit from it.

Francium Overview

Name Origin

Named for France, the nation of its discovery.

Symbol

Fr (Francium)

Description

Highly rare and unstable, radioactive metal.

Discovery

Discovered By: Marguerite Derey
Year: 1939
Location: France

Sources

Formed by decay of actinium. Chemical properties similar to cesium. Decays to radium or astatine.

Uses

Since its isotopes have such short half-lives there are no commercially significant compounds of francium.
