WebMetals & Metal Ions. Metals themselves are solid materials, some hard, other soft that will act as reducing agents. The metals have unfilled valance electron shells, and and relatively low electronegativity. This means that the metal atoms would want to lose their outer electrons and become a positively charged metal ion. WebIons of group 1 metals (Li +, Na + and K +) form soluble hydroxides. Therefore, they are identified using flame tests and not by adding sodium hydroxide solution.
