Okwenzeka emvelweni
Izimo ezijwayelekile zokushisa nokucindezela
Izimo ezijwayelekile zokushisa kanye nengcindezi amasethi ajwayelekile ezimo zezilinganiso zokuhlola okufanele zisungulwe ukuvumela ukuqhathanisa okwenziwe phakathi kwamaqoqo ahlukene wedatha.
Izinga lokushisa elijwayelekile nengcindezi nakho kubhekiselwa kuzo njengezimo ezijwayelekile. Izimo ezijwayelekile zingafaka nomswakama ojwayelekile ojwayelekile.
Izincazelo eziningi zisetshenziswa ezinye izinhlangano maqondana nezimo ezijwayelekile (bheka ithebula elingezansi); lapho kwesinye isikhathi umqondo wokushisa kwamakamelo (cishe ama-25 degrees Celsius) usetshenziswa esikhundleni se-0 degrees Celsius.
Insimbi ye-Alkali
Izinsimbi ze-alkali zingamaqembu ezinto eziseqenjini 1 lethebula lezikhathi zamakhemikhali (ngaphandle kwe-hydrogen). Lezi zinto zisebenza kakhulu futhi azivamile ukutholakala ngendlela yazo emsulwa.
Izici ezijwayelekile zalezi zinsimbi ze-alkali yilezi: okumhlophe okusasiliva, okuthambile namandla adonsela phansi aphansi. Masinyane phendula i-halogen yama-elemental.
Umhlaba wensimbi ene-alikhali
Lezi zinsimbi kubhekiselwa kuzo njengomhlaba one-alikhali ngenxa yezakhiwo zazo eziphakathi nendawo eziphakathi kwe-alkalis (i-oxide yezinsimbi zama-alkali) kanye nemihlaba engajwayelekile (i-oxide yezinsimbi zomhlaba ezingavamile).
Insimbi yenguquko
Insimbi yenguquko ingamakhemikhali angama-68 anezinombolo ze-athomu ezisuka ku-21 kuye ku-30, 39 kuye ku-48, 57 kuya ku-80 no-89 kuye ku-112. Isizathu saleli gama yisikhundla sabo kuthebula lezikhathi ngoba sithwebula ukuqala koshintsho ngenxa yokungezwa ama-electron ku-orbit orbit yesigaba d.
Uma kuchazwe ngokuqinile, izinsimbi zenguquko ziyizinto ezakha okungenani i-ion eyodwa ene-orbital egcwele (orbital) d, okungukuthi, izakhi ze-d element ngaphandle kwe-scandium ne-zinc.

Ungasisiza ukugcina lo msebenzi omuhle
Lolu hlelo lilethwa kuwe ngabafundi nabafundisi baseVietnam abanikela ngokungakhathali ukugcina izibuyekezo zokuqukethwe nokubika imininingwane elahlekile
Ukunikela ngenjongo yethu, awusizi nje ukuxhasa le webhusayithi, kodwa futhi usiza ngqo iphrojekthi yokusiza eVietnam yokwakha ama-shcools ezindaweni zasemakhaya.
Izikhangiso ze-Income form zisisiza ukuthi sigcine okuqukethwe okunekhwalithi ephezulu kakhulu kungani sidinga ukubeka izikhangiso? : D
Angifuni ukusekela iwebhusayithi (vala) - :(
