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.
Goldfish are cold water fish and do best at temperatures between 18Â°-22Â° C (65Â°-72Â° F). Several of these durable goldfish types, like the Black Moors, Shubunkins, Comets, and Common goldfish can actually tolerate temperatures a few degrees above freezing as long as the cooling drops only a few degrees a day.
