Zinc Melting Point - TheFitnessManual

Why Zn has low melting point? Zn is a very stable metal. It is not a liquid, and it does not have a boiling point. Znan is the melting temperature of Zr, which is about 1,000 degrees Celsius. Zm, is an alloy of two elements, zinc and molybdenum. The melting points of these two metals are about the same.
