he aha ka barium metala nonmetal a me ka metalloid?

Metala Bariumhe mea hoʻohalahala loa no ka pūʻulu metala honua alkaline o ka papaʻaina. He metala keʻokeʻo keʻokeʻo i ʻike ʻia no kona ʻano kiʻekiʻe a me ka hiki ke hana maʻalahi i nā pūhui. Akā ʻo ka metala barium he metala ʻole a he metalloid paha?

Akaka ka pane - he metala ka barium. Ma ke ʻano o ka hui metala honua alkaline, loaʻa iā ia nā mea metala maʻamau e like me ke kiʻekiʻe uila a me ka thermal conductivity, ductility a me ductility. ʻO Bariumis kekahi metala kaumaha me ka helu atomika kiʻekiʻe, e lilo ia i kumu hoʻohālike maʻamau o kahi metala.

ʻO kekahi o nā waiwai nui ometala bariumʻo kona maʻemaʻe kiʻekiʻe. ʻO kēia ka mea i kaulana i nāʻanoʻoihanaʻoihana likeʻole, e like me ka hanaʻana i nā'āpana, nā puaʻa a me nā mea ahi. Loaʻa ka maʻemaʻe o 99.9% ka barium metala maʻemaʻe kiʻekiʻe a hoʻohana mau ʻia i ka hana ʻana i nā paipu māmā, nā kukui fluorescent a me nā mea uila ʻē aʻe. He mea maikaʻi loa kona reactivity kiʻekiʻe a me ka conductivity.

ʻO ka metala Barium he 99.9% maʻemaʻe a ʻaʻohe haumia e hiki ke hoʻopilikia i kāna hana ma nā noi like ʻole. ʻO kēia pae o ka maʻemaʻe e hōʻoia i ka hōʻike ʻana o ka metala barium i nā waiwai i koi ʻia, e lilo ia i mea hilinaʻi a kūpaʻa i hoʻohana ʻia i nā kaʻina hana.

Ma ke ʻano o ka haku mele ʻana, loaʻa i ka metala barium kahi helu CAS o 7440-39-3, e hōʻike ana he hui kū hoʻokahi. ʻO ka maʻemaʻe kiʻekiʻe o ka metala barium a me kāna helu CAS kikoʻī e maʻalahi ke nānā a hōʻoia i ka maikaʻi a me ke kumu o ka mea, e hōʻoia ana e hoʻokō i nā kūlana koʻikoʻi i koi ʻia no ka hoʻohana ʻana i ka ʻoihana.

I ka hopena, he mea hao maoli ka metala barium a me kona maʻemaʻe kiʻekiʻe o 99.9% a me ka helu CAS7440-39-3lilo ia i mea waiwai a hilinaʻi hoʻi i nā ʻano hana ʻenehana. ʻO kona mau waiwai a me nā pae maʻemaʻe e lilo ia i mea koʻikoʻi i ka hana ʻana i nā huahana like ʻole kahi koʻikoʻi kona reactivity a me kāna conductivity.
