Rubidium is no exception to this rule, being silvery-white and melting at 39 ºC. The element has two naturally occurring isotopes. Rubidium-85 is the dominant form, accounting for 72 per cent of the total, while most of the remainder is the radioactive rubidium-87, which has a half-life of 50 billion years.

The deterioration of rubidium vapor density under 120 °C is shown in figure 5(b), which can be divided into two stages. The first stage is that the atomic vapor density of rubidium has no apparent downward trend but fluctuates wildly, for example, 0–300 h under 150 °C, 0–100 h under 200 °C, and 0–40 h under 250 °C. ...
