Francium:
Group number: I
Period: 7
Atomic number: 87
Information: Found by a woman called Marguerite Perey in France 1939. It is a very
rare metal that is HIGHLY radioactive. The isotopes for Francium are 223. And
Francium is found in the earths crust.
Fluorine:
Group number: VII
Period: 2
Atomic number: 9
Family name: Halogen family
Information: Fluorine is a yellow-brown gas that is SUPREAMLY radioactive. It is also
very poisonous and shouldn’t be inhaled. Fluorine has multiple isotopes and only one
isotope is stable (F-19)
Isotopes: any of two or more forms of a chemical element, having the same number
of protons in the nucleus, or the same atomic number, but having different numbers
of neutrons in the nucleus, or different atomic weights. There are 275 isotopes of the
81 stable elements, in addition to over 800 radioactive isotopes, and every element
has known isotopic forms. Isotopes of a single element possess almost identical
properties.
