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.
Gold has superior stability in terms of electrical or thermal conduction at low to high temperature range and harsh environmental conditions. Silver losses its characteristics when temperature varies from 20 to 100 degree centigrade. This is why, gold is best conducting material in practical and silver is highest conducting material at ideal.
