UNSUR-UNSUR LOGAM GOLONGAN 1A (ALKALI) A.     KELIMPAHAN UNSUR 1.       Kelimpahan unsur logam alkali di alam Sumber utama logam alkali adalah air laut. Air laut merupakan larutan garam – garam alkali dan alkali tanah dengan NaCL sebagai zat terlarut utamanya. Jika air lauit di luapkan, garam – garam yang terlarut akan membentuk Kristal. Selain air laut, sumber utama logam natrium dan kalium adalah deposit mineral yang di tambang dari dalam tanah, seperti halit ( NaCL), silvit (KCLl), dan karnalit ( KCl, MgCl,H 2 O). Mineral- mineral ini banyak di temukan di berbagai belahan bumi. Mineral Utama Logam Alkali Unsur SumberUtama Litium Natrium Kalium Rubidium Cesium Spodumen, LiA l(Si 2 O 6 ) NaCl KCl Lepidolit,Rb 2 (FOH) 2 Al 2 (SiO 3 ) 3 Pollusit, Cs 4 Al 4 Si 9 O 26 H 2 O Pembentukan mineral tersebut melalui proses yang lama. Mineral berasal dari air laut yang menguap dan garam – garam ...
