What element melts above room temperature but below body temperature?
Gallium
Gallium (Ga, element 31) melts at 30ºC, slightly above room temperature, but is often indicated as a liquid on periodic tables, since the solid metal literally melts when held in the hand (since body temperature is about 37ºC)….Physical States — Melting Points, Boiling Points, and Densities.

What elements can melt at room temperature?
In fact, cesium atoms are larger than those of any other element. Gallium (symbol Ga and atomic number 31), a grayish metal, melts at 303.3 K. Gallium can be melted by body temperature, as in a gloved hand….Elements That Become Liquid 25°C-40°C
- Francium.
- Cesium.
- Gallium.
- Rubidium.
Does mercury melt in your hand?
Mercury does not absorb through your skin instantly. Elemental mercury does absorb through your skin, but at a very slow pace (very slowly). As long as you don’t expose your skin to the metal too much and you wash your hands after then you would be fine.
Which element melts in your hand?
element gallium
Melts In Your Hands, Not On Your Table. The element gallium is an unexpected metal—it’s a soft, silvery-white metal that is solid at room temperature (similar to aluminum) but it can literally melt in the palm of your hand.
What metal melts in your hand?
The element gallium is an unexpected metal—it’s a soft, silvery-white metal that is solid at room temperature (similar to aluminum) but it can literally melt in the palm of your hand.
What metal melts at body temp?
Gallium is an interesting metal because it melts at body temperature, looking a lot like mercury when it’s a liquid, but safe to touch.
Which element is not liquid at room temperature?
The atomic numbers of Bromine (Br) and Mercury (Hg) are respectively 35 and 80. When the temperature is slightly warmer, there are other 4 elements found as liquids….Detailed Solution.
| Element | Symbol | Atomic number |
|---|---|---|
| Francium | Fr | 87 |
| Caesium | Cs | 55 |
| Gallium | Ga | 31 |
| Rubidium | Rb | 37 |
Is gallium the only metal that can melt?
Gallium is not the only metal that melts into a liquid near room temperature or body temperature. Francium, cesium, and rubidium also would melt in the palm of your hand.
Is gallium a liquid or solid at room temperature?
Elemental gallium is a liquid at temperatures greater than 29.76 °C (85.57 °F), and will melt in a person’s hands at a normal human body temperature of 37 °C (99 °F). It has the second-largest liquid range of any element and is one of the few metals that is liquid near room temperature (m.pt. 29.76 oC, 85.6 oF ), melting in the hand.
What elements melt at a higher temperature than room temperature?
These four elements all melt at temperatures slightly higher than room temperature. Francium (symbol Fr and atomic number 87), a radioactive and reactive metal, melts around 300 K. Francium is the most electropositive of all the elements.
Why is gallium used in high temperature thermometers?
Of the four, gallium is the only one that is neither highly reactive (rubidium and caesium) nor highly toxic (mercury) and can, therefore, be used in metal-in-glass high-temperature thermometers. It is also notable for having one of the largest liquid ranges for a metal, and for having (unlike mercury) a low vapor pressure at high temperatures.
