Chemical Principles seventh edition by Atkins, Jones, and Laverman. M H E Freeman presented by Macmillan Learning. Francium, Fr , is thought to be the most reactive of the group 1 alkali metals. However, it is radioactive, has a half-life on the order of minutes, and is available in only small amounts, making it difficult to study. Based on the properties of the other group 1 alkali metals and the periodic trends of these properties, predict the atomic radius, ionic radius of the 1 cation, and the first ionization energy of francium. Element Atomic radius (pm) Radius of 1 ion (pm) First ionization energy (kJ/mol) K 227 138 418 Rb 248 152 402 Cs 265 167 376 atomic radius of Fr : pm ionic radius of Fr : pm first ionization energy of Fr : kJ/mol

Listenbase your answer to the question on the information below.nuclear radiation is harmful to living cells, particularly to fast-growing cells, such as cancer cells and blood cells. an external beam of the radiation emitted from a radioisotope can be directed on a small area of a person to destroy cancer cells within the body.cobalt-60 is an artificially produced radioisotope that emits gamma rays and beta particles. one hospital keeps a 100.0-gram sample of cobalt-60 in an appropriate, secure storage container for future cancer treatment.which choice represents the correct product for the beta decay of the co-60? fe-60ni-60fe-61ni-61
