Ua like ke kala ma kona mau waiwai kino a me kemika me kona mau hoalauna kupaa elua ma ka hui 11 o ka papakaukau manawa, ke keleawe a me ke gula. Hoʻonohonoho ʻia kāna mau electrons 47 i ka hoʻonohonoho, e like me ke keleawe a me ke gula; ʻO ka hui 11 kekahi o nā pūʻulu liʻiliʻi i ka d-block nona kahi hoʻonohonoho paʻa o nā hoʻonohonoho electron. ʻO kēia hoʻonohonoho electron kūʻokoʻa, me kahi electron hoʻokahi i loko o ka ʻaoʻao kiʻekiʻe loa i noho ʻia ma luna o kahi subshell i hoʻopiha ʻia, no ka nui o nā waiwai kūʻokoʻa o ke kālā metala.

He mea palupalu loa ke kala, ductile a malleable hoʻololi metala, ʻoiai ua emi iki ka malleable ma mua o ke gula. Ke kala kala i loko o ka maka-i waena o ka cubic lattice me ka nui hoʻohui helu 12, kahi wale 5s electron i delocalized, e like me ke keleawe a me ke gula. ʻAʻole like me nā metala me nā pūpū-d piha ʻole, ʻaʻohe ʻano covalent nā mea hoʻopaʻa metala i ke kālā. Hōʻike kēia ʻike i ka haʻahaʻa haʻahaʻa a me ka ductility kiʻekiʻe o nā kristal kālā hoʻokahi.


ʻO ke kālā he keʻokeʻo keʻokeʻo keʻokeʻo keʻokeʻo e hiki ke lawe i ka poli kiʻekiʻe, a he ʻano ʻano nui ia i lilo ai ka inoa o ka metala i inoa kala.[8] ʻAʻole like me ke keleawe a me ke gula, ʻo ka ikehu e koi ʻia e hoʻoulu i kahi electron mai ka pahu d piha i ka sp conduction band ma ke kālā ua lawa ka nui (ma kahi o 385 kJ/mol) ʻaʻole ia e pili hou i ka absorption ma ka ʻāpana ʻike ʻia o ka spectrum, akā. ma ka ultraviolet; no laila, ʻaʻole ke kala he metala kala.[8] ʻOi aku ka maikaʻi o ke kala i mālama ʻia ma mua o ka alumini ma nā nalu nalu a pau ma mua o ~450 nm. Ma nā lōʻihi nalu i ʻoi aku ka pōkole ma mua o 450 nm, ʻoi aku ka haʻahaʻa o ke kala i ka alumini a hāʻule i ka zero kokoke i 310 nm.


Eli kala

ʻO ka mining kālā ka ʻili waiwai o ke kālā ma o ka ʻeli ʻana.
Loaʻa ʻia ke kālā ma ke ʻano maoli ʻaʻole loa e like me nā nuggets, akā ʻoi aku ka maʻamau i hui pū ʻia me ka sulfur, arsenic, antimony, a i ʻole chlorine a ma nā ores like ʻole e like me argentite (Ag2S), chlorargyrite ("horn silver," AgCl), a me galena (a ʻO ke kēpau i loaʻa pinepine i nā kālā he nui). No ka loaʻa pinepine ʻana o ke kālā i hui pū me kēia a i hui pū ʻia me nā metala ʻē aʻe e like me ke gula, pono e unuhi hou ʻia ma o ka amalgamation a i ʻole electrolysis.
Ua hana ʻia ka ʻeli kālā mai ka wā kahiko. ʻOiai ʻo ke kālā he metala makamae i hoʻohana pinepine ʻia no nā keneta, ʻoi aku ka maikaʻi o kāna ʻeli ʻana. E like me nā metala makamae ʻē aʻe e like me ke gula a i ʻole ka platinum, ʻo nā waihona kālā i ʻike hou ʻia i hoʻāla i ka holo kālā o nā miners e ʻimi ana i ko lākou waiwai. I nā kenekulia i hala iho nei, ua ʻike ʻia nā waihona nui a i ʻeli ʻia ma ʻAmelika, e hoʻohuli ana i ka ulu a me ka ulu ʻana o Mexico, nā ʻāina Andean e like me Bolivia, Chile, a me Peru, a me Kanada a me ʻAmelika Hui Pū ʻIa.

E ʻoluʻolu e kelepona mai iā mākou inā hiki iā ʻoe ke hoʻolako i nā huahana like ʻole, e hāʻawi mākou i nā kūlana maikaʻi loa no ka hui pū ʻana.
