 By Ciera Johnson
Basic Information
• Atomic Symbol: Fr

• Atomic Number: 87

• Protons: 87

• Electrons: 87

• Neutrons: 136

• Average Atomic Mass: 223
Continued
                            • Group in periodic table: 1

                            • Group name: Alkali metal

                            • Period in periodic table: 7

                            • Melting point: 27.2ºC (80.96ºF)

                            • Boiling point: 677ºC (1,250.6ºF)

• It is so radioactive and hard to work with, there is not
  much known about Francium.

• It also has no uses because it is so radioactive.
Interesting Information
• The second rarest naturally occurring
  element.
• It was the last element discovered in nature,
  that isn’t synthesis.
• The most unstable of the naturally occurring
  elements
• As little as 20–30 g (one ounce) exists at any
  given time throughout the Earth’s crust.
Discovery
   • Francium (Eka-caesium)
     was discovered in 1939 by
     Marguerite Perey of the
     Curie Institute in Paris,
     France
   • This element existence was
     predicted by Mendeleev
     during the 1870's, he called
     it eka-caesium.
Isotopes

• There are 34 identified Francium isotopes.
• There are no stable isotopes of Francium.
• Francium-223 is the most stable isotope with a
  half-life of 21.8 minutes
• The least stable ground state isotope is
  francium-215, with a half-life of 0.12 "s.
• All isotopes of Francium decay into either
  astatine, radium, or radon.
Atomic Structure.
