Te Hononga Taurite: Ngā Kaupapa Taketake me ngā Whakamahinga i roto i te Matū
Ko ngā hononga honohono tētahi o ngā momo hononga matū tino taketake, tino nui hoki i roto i te matū. I roto i ō tātou oranga o ia rā, ka tūtaki tātou ki ngā matū i hangaia e ngā hononga honohono i roto i ngā āhuatanga maha, mai i te hau e manawahia ana e tātou ki te kai e kainga ana e tātou. I roto i tēnei tuhinga, ka matapakihia e tātou ngā hononga honohono, tae atu ki ō rātou kaupapa matua, te āhua o te hanganga, ngā āhuatanga ka puta mai, me ō rātou whakamahinga i roto i te matū me te oranga o ia rā.
Ngā Kaupapa Taketake o te Hononga Taurite
Ko te hononga kovalent he momo hononga matū e hangaia ana ina whakamahia ngātahitia e ngā ngota e rua, neke atu rānei, ngā takirua irahiko hei whakatutuki i te pumau hiko, e whai ana i te ture octet, arā, ko te ia o ngā ngota kia waru ngā irahiko i roto i ō rātou anga o waho. Ko te tikanga ka puta tēnei hononga i waenga i ngā ngota kore-whakarewa.
Ngā Irahiko Valence me te Pūmautanga
He mahi nui tā ngā irahiko valence, arā, ngā irahiko kei roto i te anga o waho o te ngota, ki te hanganga o ngā hononga covalent. Ka tohatohahia e ngā ngota ō rātou irahiko valence kia tutuki ai he whirihoranga irahiko pumau ake. Hei tauira, e rua ngā ngota hauwai (H) he irahiko valence kotahi kei ia ngota. Mā te tohatoha i ēnei irahiko, ka tutuki i ia ngota hauwai he whirihoranga pumau, he rite ki te herium (He).
Te Hanganga o ngā Here Hononga
Ka taea te whakamārama i te hanganga o ngā hononga honohono mā te whakamahi i ngā ariā o ngā porowhita ngota me te ariā porowhita ngota. Ina tata ngā ngota e rua, ka taupatupatu ō rātou porowhita valence, ka taea ai e rātou te tohatoha i ngā irahiko hei hanga i tētahi hononga pumau. Ka taea e ngā hononga honohono te:
– Ngā hononga takitahi, arā, ko te takirua irahiko e whakamahia ana e ngā ngota e rua (hei tauira, ko te H₂, he ngota hauwai e rua).
– Ngā hononga takirua, arā, ko ngā ngota e rua e whakamahi tahi ana i ngā takirua irahiko e rua (hei tauira, O₂, te hāora ngota).
– Ngā herenga takitoru, arā, e toru ngā takirua irahiko e whakamahia ana e ngā ngota e rua (hei tauira, N₂, he ngota hauota).
Ngā Āhuatanga o ngā Here Honohono
He maha ngā āhuatanga ahurei o ngā hononga honohono e wehewehe ana i a rātou i ētahi atu momo hononga matū, pērā i ngā hononga ionic. Anei ētahi āhuatanga nui o ngā hononga honohono:
Te āhua o te polarity
Ka taea ngā hononga honohono
– Ko te irahiko kore-poari: Ka hangaia i waenga i ngā ngota he rite tonu, he tino ōrite rānei ō rātou irahiko. Ka tohaina ōrite ngā irahiko i waenga i ngā ngota e rua, hei tauira ko ngā ngota rua-atomic pērā i te H₂, te N₂, me te O₂.
– Ngā herenga kōtuitanga pōra: Ka puta ina he rerekētanga nui te kaha hiko o ngā ngota e rua. Ka roa ake te wā e noho ana ngā irahiko ki te taha o te ngota he kaha ake te hiko, ka hua ake he utu pai, he utu kino hoki ki taua ngota. Ko tētahi tauira noa ko te ngota wai (H₂O), he kaha ake te hiko o te hāora i te hauwai.
Pūngao Here
He pūngao hononga motuhake tō ia hononga honohono, arā, te pūngao e hiahiatia ana hei motu i te hononga. Ko te pūngao hononga he tohu mō te kaha o te hononga, ā, ko ngā hononga takirua me ngā hononga takitoru he nui ake te pūngao hononga i ngā hononga takitahi nā te mea he nui ake ngā irahiko e tohaina ana e rātou.
Te Roa o te Here
Ko te roa o te hononga honohono ko te tawhiti i waenganui i ngā karihi o ngā ngota e rua e honoa ana. He poto ake te roa o te hononga mō ngā hononga takirua, ā, he poto ake anō hoki mō ngā hononga takitoru i ngā hononga takitahi.
Ngā Whakamahinga me ngā Pānga o ngā Herenga Taurite
He mea nui te mahi a ngā hononga honohono i roto i ngā āhuatanga maha o te ao me te hangarau. Anei ētahi o ngā whakamahinga me ngā pānga nui o ngā hononga honohono:
Mea Ora
Ko ngā matū waro, koinei te pūtake o ngā mea ora katoa, he mea hanga nui mai i ngā ngota ngota me ngā hononga honohono. Ka hangaia e te waro, te hauwai, te hāora, te hauota, me ētahi atu huānga he momo hononga honohono hei hanga i ngā matū waro pērā i te pūmua, te warowaihā, te ngako, me ngā waikawa karihi. Hei tauira, ko te DNA, e penapena ana i ngā mōhiohio ira, he mano tini ngā ngota e honoa ana e ngā hononga honohono i roto i te hanganga porowhita rua.
Matū Rongoā
I roto i te matū rongoā, mā te mārama ki ngā hononga honohono ka taea e ngā kaipūtaiao te hoahoa me te hanga rongoā e taunekeneke ana ki ngā whāinga koiora i roto i te tinana. He maha ngā rongoā e mahi ana mā te hanga hononga honohono me ngā whākōkī, ngā kaiwhakawhiwhi rānei hei aukati, hei whakarerekē rānei i ngā mahi koiora.
Matū Rauemi
I roto i te matū rauemi, ka whakamahia ngā matū i hangaia e ngā hononga honohono hei hanga rauemi me ngā āhuatanga motuhake. Hei tauira, ko ngā pūmua, he mekameka roa o ngā ngota ngota e herea ana e ngā hononga honohono, ka whakamahia i roto i ngā ahumahi maha, pērā i te kirihou, te kakahu, me te rapa. Waihoki, he whānui ngā tono o ngā rauemi hanganga-waro pērā i te graphene me ngā nanotubes waro i roto i ngā hikohiko, ngā rauemi hiato, me te nanotechnology.
Matū Kore-Pararopi
I roto i te matū kore-waro, he mea nui anō hoki ngā matū maha i hangaia mā te hononga irahiko. Hei tauira, ka hangaia ngā waikura whakarewa maha e whakamahia ana i roto i te whakatere me ngā pūoko hau mā roto i ngā hononga irahiko i waenga i te whakarewa me te hāora. Hei tāpiri, ka whakamahia ngā silicates me ngā aluminates, he hanganga matatini toru-ahu me ngā hononga irahiko, i roto i ngā uku me ngā rauemi hanga.
Whakamutunga
He mea nui ngā hononga honohono ki te matū, e āhei ai te hanganga o ngā ngota maha e hanga ana i te ao e karapoti nei i a tātou. Mai i ngā hanganga o ngā ngota waro matatini ki ngā rauemi auaha i roto i te hangarau matatau, he whānui, he mea nui hoki te mahi a ngā hononga honohono. Ehara i te mea he mea nui anake te mārama ki ngā ariā me ngā āhuatanga o ngā hononga honohono i roto i te ako matū, engari i roto hoki i ōna tono mahi rerekē i roto i te oranga o ia rā. Mā te haere tonu ki te ako me te tūhura i ngā āhuatanga o ngā hononga honohono, ka taea e tātou te hanga me te whakawhanake i ngā hangarau hou e whai hua ai te pumau me te whanaketanga o te hapori tangata.
