Silver freezes from a liquid into a solid at a temperature of approximately 1,762 degrees Fahrenheit. Conversely, silver also melts from a solid into a liquid when heated past that temperature. Because of this high melting point, silver is a solid at room temperature.
Silver's boiling point is similarly high, at approximately 3,925 degrees Fahrenheit. While the trends governing the melting and boiling points of elements are very complex, transition metals in general tend to melt and boil at higher temperatures than the metalloids or the nonmetals. As silver is a transition metal, its high freezing point should be expected.
