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.
Simply place the piece of gallium in the palm of your hand and let the warmth of your body heat do the work! The melting point of gallium is 29.76 Â°C (85.57 Â°F), so it will readily melt in your hand or in a very warm room. Expect this to take around 3-5 minutes for a coin-sized piece of metal.
