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.
As the temperature is increased they will melt and become liquids. Each element melts at a different temperature, called it's melting point. Hydrogen melts at -259 degrees Celsius. Mercury melts at -39 degrees Celsius. Iron melts at 1,535 degrees Celsius. As the temperature is increased still further, each element will boil and become a gas. Each element boils at a different temperature, called the boiling point.
