Lead has the highest atomic number of any stable element and concludes three major decay chains of heavier elements. The temperature at which vaporization (boiling) starts to occur for a given pressure is also known as the saturation temperature and at this conditions a mixture of vapor and liquid can exist together. There are over 100 different borate minerals, but the most common are: borax, kernite, ulexite etc. The pressure at which vaporization (boiling) starts to occur for a given temperature is called the saturation pressure.
