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.
Whenever gold is in the solid state, it has definite shape and volume. But there's nothing especially natural about that state. When a piece of gold gets warmer than 1948Â°F, it turns to liquid, gets runny, makes puddles, and takes the shape of whatever you pour it into, just like water. AND ... if that puddle of gold gets warmer than 5378Â°F, it evaporates, becomes gold vapor ... a gas ... and no longer has
