Discuss the key atomic properties (charge, shielding, orbital configuration, etc) that contribute most significantly to following periodic trends1) Atomic and ionic size2) Physical properties3) Chemical propertiesSelect an example of a transition metal that does not follow the orderly filling of electrons. Propose an explanation for this exception and speculate on what chemical or ionic properties you would expect to see.
