Define what are the identities of the three particles

Reference no: EM13518006

Three particles have the same electron configuration. One is a cation of an alkali metal, one is an anion of the halide in the third period, and the third is an atom of a noble gas. What are the identities of the three particles(including charges)? Which particle should have the smallest atomic/ionic radius, which should have the largest and why?
