ʻO ka nā loulou hao He ʻano liona kemika lākou e kū ana ma waena o nā ʻoma o ka metala like, a ma o ia mea e loaʻa ai nā hanana molekoki paʻa loa, mai ke kumu o ka ʻĀtoma hui pū lākou a hoʻomaka lākou e kaʻana like i nā electron valence.
Haʻalele nā mea hope i kā lākou huina maʻamau a noho mau a puni ka pūʻulu o nā nukelea, e like me ke ʻano o ke ao, a ʻo ka ʻumeʻa ma waena o kā lākou mau koina maikaʻi ʻole a me nā koina maikaʻi o ka nuklei ka mea e paʻa paʻa ai ka hoʻonohonoho.
I kēia ala, ʻo ka paʻa hao he mea paʻa a me ka paʻa mua i nā mika, ka mea hiki ke hana ʻia ma waena o nā ʻoma o nā ʻano like a me ke ʻano o ke kinikini. ʻAʻole hoʻi e huikau kēia ʻano o nā loulou ionic a i ʻole ka covalent, ʻoiai me ka mea hope hiki iā ia ke kaʻana like i kekahi mau ʻaoʻao mai ka hoʻopili ʻana o nā atoms i kā lākou mau uila uila i kekahi nui.
Nā waiwai o nā mea hao
I ke ʻano o nā paʻa hao pono nā ʻano pono o nā metala, e like me ka paʻa a me ka paʻakikī o kā lākou mea, kona malleability a hoʻonanea, kāna maikaʻi conduction o ka wela a uila paha, a me ko lākou alohilohi hoʻi, ʻoiai lākou e hoʻihoʻi i ka ʻaneʻane o ka ikehu uila e hoʻokau iā lākou.
Hoʻonohonoho ʻia nā ʻātoma i hoʻohui ʻia e nā ʻano o nā lou o ka lepe ʻekolu-dimensionally i ka hexagonal, nā cubic, a i ʻole nā ʻano ʻē aʻe: e like me ka hihia o ka mercury, no ka laʻana, he wai i ke ana wela o ka lumi, hana ʻia ka hui atomic ma o nā ʻano hana like ʻole a ʻae i ka hoʻokumu ʻia ʻana o nā kulu āpau o kēia metala.
Nā laʻana o nā paʻa hao
Kū pinepine pinepine nā mea hao i ka honua atomic o nā metala, no laila ʻo kēlā me kēia mea hao hao kūpono he laʻana kūpono o ia mau mea, ʻo ia hoʻi:
- Nā loulou ma waena o nā atoms Silver (Ag).
- Nā loulou ma waena o nā ʻĀtoma Gula (Au).
- Nā loulou ma waena o nā atom o Cadmium (Cd).
- Nā loulou ma waena o nā ʻoma hao (Fe).
- Nā hoʻopaʻa ma waena o nā ʻoma ʻo Nickel (Ni).
- Nā hoʻopaʻa ma waena o nā ʻātoma Zinc (Zn).
- Nā hoʻopaʻa ma waena o nā ʻoma o Copper (Cu).
- Nā pilina ma waena o nā atom o Platinum (Pt).
- Nā loulou ma waena o nā ʻĀtoma Aluminium (Al).
- Nā loulou ma waena o nā atom o Gallium (Ga).
- Nā hoʻopaʻa ma waena o nā ʻoma o Titanium (Ti).
- Nā hoʻopaʻa ma waena o nā ʻoma ʻo Palladium (Pd).
- Nā loulou ma waena o nā ʻātoma kēpau (Pb).
- Nā hoʻopaʻa ma waena o nā ʻĀtoma Iridium (Ir).
- Nā hoʻopaʻa ma waena o nā ʻoma atom o Cobalt (Co).
Hiki ke lawelawe iā ʻoe
- Nā laʻana o nā Bond Ionic
- Nā laʻana o nā Bond Covalent
