Helu CAS 7439-90-9 Krypton kūʻai nui. Mea hoʻolako Krypton

ʻO ka helu CAS 7439-90-9 e hōʻike ana iā Krypton, he kinoea maikaʻi i ʻike ʻia no kāna mau waiwai kūʻokoʻa a me kekahi mau noi kūikawā. Eia nā hiʻohiʻona nui a me nā kikoʻī e pili ana iā Krypton:
Hoailona Kimia: Kr
Nā waiwai kino:
ʻAno: ʻO Krypton kahi ʻala ʻole, kala ʻole, kinoea inert ma ka lumi wela a me ke kaomi maʻamau.
Helu ʻAtoma: 36
Nuipa ʻAtoma: 83.798 u (nā ʻāpana ʻātoma i hui ʻia)
Puni paila: -153.4°C (-244.1°F) ma 1 atm
Lae hehee: -157.4°C (-251.3°F) ma 1 atm
Density: Ma kahi o 3.75 mau manawa i ʻoi aku ka kaumaha ma mua o ka ea ma STP (Standard Temperature and Pressure)
Nā waiwai kemika:
Non-Reactivity: ʻOiai he kinoea maikaʻi ʻole, ʻaʻole hiki ke hana ʻia ʻo Krypton a ʻaʻole hiki ke hana i nā pūhui ma lalo o nā kūlana maʻamau.
Paʻa: Paʻa loa ma muli o kāna mau pūpū electron piha.
Nā hoʻohana a me nā hoʻohana:
Ke kukui: Hoʻohana ʻia ʻo Krypton i kekahi mau ʻano o nā kukui ʻoi loa, me nā uila kiʻi a me nā ʻōpuʻu kukui kūikawā e like me nā mea i hoʻohana ʻia i nā kukui a me nā kukui holo mokulele, ma muli o kona hiki ke hoʻokuʻu i ke kukui keʻokeʻo keʻokeʻo ke hoʻohauʻoli i ka uila.
Nā Lasers: Hoʻohana ʻia nā lasers Krypton i nā noi like ʻole e like me ke ʻoki laser, spectroscopy, a me ka holography.
Welding: Hoʻohui ʻia me ka argon, hoʻohana ʻia ia ma ke ʻano he kinoea pale i kekahi mau ʻano o ka welding e pale aku i ka weld wahi mai ka ʻino o ka lewa.
Radiometry a me Photometry: Hana ia ma ke ʻano he maʻamau kuhikuhi no ka calibration o kēia mau mea ana.
Ka Leak Detection: Ma muli o kona kaumaha molecular kiʻekiʻe a me ka ʻona ʻole, hoʻohana ʻia ka krypton ma ke ʻano he kinoea tracer no ka ʻike ʻana i nā leaks i nā ʻōnaehana sila.
Nā hiʻohiʻona kūikawā:
Rare: He kinoea laha ole ka Krypton ma ka lewa o ka Honua (ma kahi o 1 hapa miliona ma ka leo).
Monatomic: Ma lalo o nā kūlana maʻamau, aia ka krypton ma ke ʻano he mau ʻātoma pākahi ma mua o nā mole.
Inā makemake ʻoe i kēlā mau huahana, e ʻoluʻolu e hoʻokaʻaʻike mai iā mākou!
