Elaborate on what can be learned about the properties by the location of element on the periodic table. use atomic number 13 as an example. a) it is a non-metal, has 3 valence electrons, becomes a cation with a -3 charge, and is brittle, moldable, and non-conductive. b) it is a metalloid, has 3 valence electrons, becomes a cation with a -5 charge, and is workable, inelastic, and non-conductive. c) it is a main group metal, has 3 valence electrons, becomes a cation with a +3 charge, and is ductile, malleable, and conductive. d) it is a transition metal, has 1 valence electrons, becomes a cation with a +1 charge, and is ductile, malleable, and conductive. eliminate
