4 Facts
4.1 Interesting Facts
- The most stable isotope of Nobelium metal is No-259.
- No-259 has a half-life of fifty-eight minutes.
- At room temperature mercury is found in a liquid state.
- A coin of pound or rupees floats in mercury.
- Because of its low melting point and boiling point it is used in thermometers.
