Given this experimental data, Rutherford naturally considered a planetary-model atom, the Rutherford model of 1911 â electrons orbiting a solar nucleus â however, said planetary-model atom has a technical difficulty.
1 Goldâs melting point is at about 1,943 degrees Fahrenheit, which means you will need temperatures that hot to melt it. 2  Thus, it's very important that you don't just choose any container. 3  In addition to a crucible, you will need a pair of tongs to move the crucible and hold it.
Best Answer: The melting point of pure nickel is 2651Â° F(1455Â° C). This temperature is much higher than the melting points of most base metals. Yet, according to the definition of brazing, base metals must be joined at a brazing temperature below their melting points.
