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.
The resistivity of gold is 2.44 x 10-8 Ïâ¢m at a temperature of 20Â°C. A gold wire, 0.5 mm in diameter and 44 cm long, carries a current of 380 mA.
