(they can be drawn into wire). Metalloids are useful in the semiconductor industry. The applications of potassium include as a heat medium for some nuclear reactors, as a nutrient in fertilizers and fireworks in the form of potassium nitrate. In 1807, Humphry Davy used the electrolysis process to isolate and recover potassium from potash. The arrangements of electrons above the last (closed shell) noble gas. Oxides of metals are characteristically solid at room temperature. Luster: Silicon for example appears lustrous, but is not malleable or ductile (it is brittle - a characteristic of some nonmetals).
