In 1913 Niels Bohr proposed a new model of the atom that included quantized electron orbits: electrons still orbit the nucleus much as planets orbit around the sun, but they are only permitted to inhabit certain orbits, not to orbit at any distance.
About reports the melting point of gold is 1,064.43 degrees Celsius. The melting point of a solid is the temperature at which it becomes a liquid. Gold's boiling point is 2,807 degrees Celsius.
Some metals melt at lower temps than others. Tin becomes liquid at 231.8ËC (447.8Ë F); at the other end of the spectrum, tungsten has the highest melting point of any metal: 3,422Ë C (6,192Ë F). Somewhere in the middle is mercury, which stays in a liquid state until its temperature drops to -40Â°. âA metal is full of bonds between the atoms that make it up,â explains Carter. âWhat determines a materialâs melting point has everything to do with the energy associated with the bonds.
