Does francium react with hydrogen?
Reaction of francium with acids I’m not sure this reaction has ever been done, but one would predict that francium metal will dissolve very readily in dilute sulphuric acid to form solutions containing the aquated Fr(I) ion together with hydrogen gas, H2.
What are the elements of francium?
It is the second-most electropositive element, behind only caesium, and is the second rarest naturally occurring element (after astatine). The isotopes of francium decay quickly into astatine, radium, and radon….

How is francium made?
Francium is obtained by the neutron bombardment of radium in a nuclear reactor. It can also be made by bombarding thorium with protons.
What is CS on the periodic table?
cesium (Cs), also spelled caesium, chemical element of Group 1 (also called Group Ia) of the periodic table, the alkali metal group, and the first element to be discovered spectroscopically (1860), by German scientists Robert Bunsen and Gustav Kirchhoff, who named it for the unique blue lines of its spectrum (Latin …
What is hydrogen made out of?
Composed of a single proton and a single electron, hydrogen is the simplest and most abundant element in the universe.
What are the essentials of francium?
Francium: the essentials. Francium occurs as a result of α disintegration of actinium. Francium is found in uranium minerals, and can be made artificially by bombarding thorium with protons. It is the most unstable of the first 101 elements. The longest lived isotope, 223 Fr, a daughter of 227 Ac, has a half-life of 22 minutes.
How is francium formed?
Francium occurs as a result of α disintegration of actinium. Francium is found in uranium minerals, and can be made artificially by bombarding thorium with protons. It is the most unstable of the first 101 elements.
How many protons and electrons are in francium?
Francium is a 87. chemical element in the periodic table of elements. It has 87 protons and 87 electrons in the atomic structure. The chemical symbol for Francium is Fr.
What is the chemical symbol for francium?
The chemical symbol for Francium is Fr. The atom consist of a small but massive nucleus surrounded by a cloud of rapidly moving electrons. The nucleus is composed of protons and neutrons. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z.
