Mea hao a me ka 'ole-mea hao waiwai: papaʻaina e like me ke alakaʻi

Ka manaʻo o "ke hooheheeia" a pau Hehe ho i au iaʻu iho. Ka hao, i ke kala, i ke gula, keleawe, kēpau. i loaʻa kēia mau inoa i loko o ka kūkala nūhou mau, no laila, mau kanaka e e noi ninau e pili ana i ka mea hiki ke hooheheeia. Aka, ka mea makemake e hana ino i ka aʻo e pili ana i na mea hiki ke hooheheeia , mai ka oiai ua ike mai o ka chemist a me ka physicist, ina e makemake e malama i ka manao o ka'ōnaehana nānaina o ko ke ao nei. A like no me ka completeness o ka ike ma keia kumuhana makemake ole e hana ino i ke aʻo e pili ana i nā pūʻulu - 'ole-i eliiaʻi a me metalloids. He aha ka ka metala a me ka ole-mea hao waiwai?

Inā ka paʻa ua summed

Ole-ke hooheheeia he oi pohihihi, oiaio hoi i ka poe e ole hoomanao kula kemika, no laila, noʻonoʻo ma luna o nā waiwai o ka ole-mea hao a me ka mea hao, pakahi, pono e manaʻo me ke ku pono. Ka mea i oe e ole hoomanao, aole ka i hilahila, ke kanaka lolo mea pono, e malama i ka 'ike ma ka manaʻo e, aole ia e pono i kela lā. No laila, ua helu i ka waiwai o ka ole-mea hao, a me ke kākau manaʻo ma luna o lākou, e hana ia oi maopopo.

No wela,ʻaʻohe uila

Ole-ke hooheheeia ino ke hooheheeia hoʻomaka uila a me ka wela. Nolaila, pālolo Mug, mua, paʻa wela maikaʻi ma mua o mea hiki ke hooheheeia, a me ka lua, i ka manawa kūpono e puhi i kou lima ma luna o ka Mug o ka loa emi o ke koa o ka hao Mug. A e hoomanao, maluhia huki aku, mai ke kumu mai o ka loli ana o kanaka hiki ole e kala pono me ka mea hiki ke hooheheeia mea. Akā, i ka laau hiki ke hana, kalapona ma ka lāʻau - nonmetal. I ka waiwai o ka mea hiki ke hooheheeia - e hoʻomakaʻikena maikaʻi mea hao waiwai nā haʻahaʻa conductivity.

Fragility ole plasticity

Pure waiwai mai ka 'ole-ke hooheheeia nui brittle a nui pinepine nei i loko o ka paa moku'āina i loko o ka pauka palapala. Metal forging, hiki ke 'ole ma ka wela, na mea paahana, a me ka loa hana paʻahau palapala (hoʻohana i kēia mea e like ai ma ka foundry hana). Ole-ke hooheheeia mai i hoʻokō '. Ole-ke hooheheeia pinepine, a hiki ina ka mea ana i loko o ka palapala o ka apana, e no i ka haʻahaʻa nuʻa a pinepine aku i loko o ka palapala o porous.

Table like me ka palapala 'ana o ka wahi

Inā e "hele" i ka papa'āweʻaweʻa kemika papa, mai haʻalele i ka akau, oe, e hai i ka hoʻokāʻoi i ka ole-mea hao waiwai, mai haʻalele i ka akau. Helium - ka nui "maikaʻi 'ole-ke hooheheeia." Akā, inā e hele aku ia i ka papaʻaina, ka mea hao waiwai o ka mae wale. I eliiaʻi no hoi lilo houʻano pākīkē meʻoe, mai luna iho o ka papa'āweʻaweʻa kemika papaʻaina. Ke'ī mai, i ka papa'āweʻaweʻa kemika papaʻaina ke'ōlelo pākīkē mai lawe waiwai o ka poe noonoo ole 'ona, oia o nā'ātoma o pakahi hehee wale. Waiwai "ma ka waena," i kapaia metalloids a i hoʻohana pinepine i ka uila 'enekinia, me semiconductors.

Ka hoʻohana a non-i eliiaʻi

General laulā no a pau na ole-ke hooheheeia hana ole. Kēlā i kona mau "specialization", like ole-mea hao lako -ʻokoʻa. Inert kinoea i hoʻohana no foxmike hoʻolaha, selenium - no toners ma ke pai hana, luaipele mea i loko o ka ń. Mākou mau halawai i loko o kā lākou mau kela la i keia ola a me nā pono hana, a iloko o ka ole-ke hooheheeia nā mea loaʻa.

Ke'ī mai, ke ole-mea hao waiwai, e like mea hiki ke hooheheeia, hiki ke wānana ma ka papa'āweʻaweʻa kemika papaʻaina. A me kēia mau lauana e loa hana hoihoi, no ka mea, i ka papaʻaina hale kūʻai i nō nui undiscovered mea huna e ā nā kānakaʻepekema, e nana i kahi i loko o ka hala, a hiki mai i loko o ka wā e hiki mai. No hoihoi i loko o ka wā e hiki mai ana o metalloid.
