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 physical state of gold at room temperature (25 degrees centigrade) is solid. In its solid state it is a soft, malleable metal. The melting point of gold is 1063 degrees C. At this temperature it will melt to a liquid.
