118 are chemical elements in the periodic table 92 are natural, while the rest are artificial or synthetic. Within these last 26, one in particular draws much attention. And as in the OjoCientífico are so curious, we will introduce today all you need to know on the Gallium, one of the strangest most intriguing elements bamboo dish drying rack of the Periodic Table.
Gallium is a strange artificial chemical element, which becomes a liquid at temperatures bamboo dish drying rack close to ambient. This element expands upon solidification and found as a trace element in coal, bauxite and certain other minerals.
In the same way that the mercury and rubidium Cesium will occur gallium melts and turns into liquid to be exposed to heat and hardly is commonly used in semiconductor and as a component of some alloys with low point fusion.
Gallium has a solid consistency and normal temperatures is soft and can be cut easily with any knife. In water and in the air, but is stable in acid and other alkali bamboo dish drying rack dissolves easily.
This element is classified as a solid and is situated in the section of "other metal" of the groups 13, 14 and 15 of the periodic table. These metals are solid, most have a relatively high density and are also opaque.
There is an element found in nature, whether as a trace element in coal, bauxite and some other minerals. Properties Symbol: Ga Atomic bamboo dish drying rack Number: 31 Atomic Mass: 69,723 uma Melting point: 29.78 C Boiling Point: 2403.0 C Number of Protons / Electrons in Gallium: 31 Number of neutrons in the Gallium: 39 Crystal Structure : orthorhombic Density: 293 K: 5.907 g/cm3 Color: White / Silver
Well, now we leave you with this different video to know a little more about the Gallium and have some ideas for fun playing with science. Furthermore, there is nothing to fear, despite the Gallium seem much mercury, it differs from this inter alia not toxic.
