Four elements are represented by the letters J, K, L, and M. the four elements are all active metals and have the same number of valence electrons and a filled valence sub-shell(s, p,d, f). Element J is the most metallic and has electrons in five energy levels. Elements M has a larger atomic radius than either K or L but is smaller than J. L has higher first ionization energy than does K. identify the elements. Enter the element symbol
