| 説明 | Gallium (Ga) is # 31 on the Periodic Table of Elements. Elemental gallium is a silvery-gray metal. If resting in one's palm, a solid gallium sample will melt as it warms up. Gallium is obtained as a by-product of processing bauxite, an aluminum ore rock.Thirty isotopes of gallium are known - two occur naturally. About 60% of Ga is gallium-69 and the other ~40% is gallium-71.-----------------------------Info. at:en.wikipedia.org/wiki/Galliumanden.wikipedia.org/wiki/Isotopes_of_gallium |
