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.
ArgentiumÂ® Silver has a melting point around 60 degrees. lower than traditional sterling. Similarly, it has a lower. annealing temperature range of 1050Â°F to 1150Â°F. ArgentiumÂ® Silver glows a paler red when heated to. annealing temperature. In practice, I find the paler glow hard to see, and it is easy to.
