The last metal to be officially discovered is francium, which was identified in 1939 by Marguerite Perey at the Curie Institute in Paris. Francium is highly radioactive and is extremely rare in nature, making it difficult to study. It is classified as an alkali metal and is produced from the decay of actinium. Due to its instability and short half-life, francium has limited practical applications.
