Imagine you are given a mystery element. it is , however a discovered and known element . you may perform a maximum of two observations or tests to determine its identity. time and money is critical. getting by with a single test is preferable. pick your two tests , number them as 1 and 2 and justify why you think these two will certainly be enough ( and why the first could be enough by itself). the available tests are classification into metal , not metal , or metalliod, count of valence electrons , count of electron shells , atomic radius , electronegativity , first ionization energy , melting point , and boiling point
