Iimeko eziqhelekileyo zobushushu kunye noxinzelelo

Imeko esemgangathweni yeqondo lobushushu noxinzelelo ziiseti eziqhelekileyo zeemeko zemilinganiselo yokulinga ekufuneka isetelwe ukuvumela uthelekiso olwenziwe phakathi kweeseti ezahlukeneyo zedatha.

Ubushushu obuqhelekileyo kunye noxinzelelo kukwabizwa ngokuba ziimeko eziqhelekileyo. Iimeko eziqhelekileyo zinokubandakanya ukufuma okuqhelekileyo okuhambelana.

Iinkcazo ezininzi zisetyenziswa kweminye imibutho ngokubhekisele kwiimeko eziqhelekileyo (jonga kwitheyibhile engezantsi); apho ngamanye amaxesha umxholo wobushushu begumbi (malunga nama-25 degrees celcius) usetyenziswa endaweni ye-0 degrees celcius.

Isinyithi sealkali

Izinyithi zealkali ngamaqela ezinto kwiqela 1 letheyibhile yamaxesha eemichiza (ngaphandle kwehydrogen). Ezi zinto zisebenza kakhulu kwaye kunqabile ukuba zifumaneke kwifomu yazo emsulwa kwindalo.

Iimpawu eziqhelekileyo zezi zinyithi zealkali zezi: isilivere emhlophe, ithambile kunye nomxhuzulane othile ophantsi. Ngokukhawuleza phendula kwi-halogen yesiqhelo.

Isinyithi emhlabeni

Ezi zinyithi zibizwa ngokuba ngumhlaba we-alkaline ngenxa yeendawo zabo eziphakathi kwendalo phakathi kwe-alkalis (i-oxide ye-alkali yensimbi) kunye nomhlaba onqabileyo (i-oxide yezinto ezinqabileyo zomhlaba).

Utshintsho lwesinyithi

Isinyithi esiguqukayo singama-68 eekhemikhali ezinamanani eathom ukusuka ku-21 ukuya ku-30, 39 ukuya kuma-48, 57 ukuya ku-80 kunye no-89 ukuya ku-112. yee-elektroni kwi-atomic orbit yeklasi d.

Ukuba kuchazwe ngokungqongqo, isinyithi esiguqukayo zizinto ezenza ubuncinci i-ion enye enendawo ye-orbital (orbital) ezalisiweyo, okt, d-element element ngaphandle kwe-scandium kunye ne-zinc.

Ulwazi olunomdla kuphela ngabantu abambalwa abayaziyo


Ingeniso yefom yentengiso isinceda ukugcina umxholo kunye nomgangatho ophezulu Kutheni kufuneka sibeke izibhengezo? : D
