Francium, Fr, is a radioactive element found in some uranium minerals and is formed as a result of the decay of actinium. a) What are the electron configurations of francium AND its predicted most common ion? b) It has been estimated that at any one time, there is only one (1.0) ounce of francium on earth. Assuming that is true, what number of francium atoms exist on earth? c) The longest -lived isotope of francium is 223Fr. What is the total mass (in grams) of the neutrons in one atom of this isotope?
