Identifikasi Kelimpahan Unsur
GAS MULIA
![Page 2: Identifikasi Kelimpahan Unsur](https://reader036.vdokumen.com/reader036/viewer/2022071700/55260c954a795993488b4e49/html5/thumbnails/2.jpg)
Helium
• Identifikasi :– Helium dapat diperoleh dengan jalan
pemisahan dari gas alam, sebab pada sumber gas alam tertentu terdapat Helium dalam jumlah yang cukup banyak
– Helium (He) adalah unsur kimia yang tak berwarna, tak berbau, tak berasa, tak beracun, hampir inert, monatomik

Neon
• Identifikasi :– Neon termasuk kelompok gas mulia yang tak
berwarna dan lembam (inert)– Zat ini memberikan pendar khas kemerahan
jika digunakan di tabung hampa (vacuum discharge tube)

Argon
• Identifikasi:– Argon is colorless, odorless, tasteless and
nontoxic in both its liquid and gaseous forms. Argon is inert under most conditions and forms no confirmed stable compounds at room temperature.(bahasa indonesia nya hampir sama ama Helium)
– Bentuk kelimpahan Argon : argon fluorohydride (HArF)

Krypton
• Identifikasi:– A colorless, odorless, tasteless noble gas.– Krypton can also form clathrates with water
when atoms of it are trapped in a lattice of the water molecules.(aq gtw arti clathrates n lattice, tolong cariin)

Xenon
• Identifikasi :– A colorless, heavy, odorless noble gas, xenon
occurs in the Earth's atmosphere in trace amounts. Although generally unreactive, xenon can undergo a few chemical reactions such as the formation of xenon hexafluoroplatinate, the first noble gas compound to be synthesized.(easy kn buat ditranslate?)

Radon
• Identifikasi :– Radon is a colorless, odorless, tasteless,
naturally occurring, radioactive noble gas that is formed from the decay of radium.(decay = penguraian)
– Pada suhu dan tekanan ruang, radon tidak berwarna tetapi apabila didinginkan hingga membeku, radon akan berwarna kuning, sedang kan radon cair berwarna merah jingga.

Keliatan nya tugas aq hampir sama dengan sifat fisik unsur gas mulia, tapi menurut buku emang kae gitu. Karena gas mulia itu adalah GAS. Hho.
Siiip? woookeeehh
