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 melts at a much cooler temperature â about 2,000 degrees Fahrenheit â but thatâs enough to survive most house fires. Platinum jewelry is the priciest, so itâs a good thing that the metalâs melting point is just higher than 3,200 degrees Fahrenheit. Sapphire and Ruby also possess extremely high melting points.
