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.
