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.
The metal with the highest melting point is tungsten, which melts at 6,188 degrees F (3,420 degrees C). But the highest melting point of any substance belongs to carbon, which melts at 6,386 degrees F (3,530 degrees C).
