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.
Melting point of Gold = 1064.18 Â°C   Melting point of Silver = 961.78 Â°C   Melting point of Copper = 1084.62 Â°C    Of cause an alloy of all three would probaâ¦bly have a eutectic  melting behavour.
