Thaum nws poob electron(s) nws ua raug nqi zoo thiab hu ua cation. Calcium atom nrog electron kev npaj K (2), L (8), M (8), N (2) poob ob lub electrons los ntawm nws lub plhaub sab nraud (N plhaub) thiab cov ntaub ntawv zoo ions hu ua Calcium , Txa2+ ion.
Ib yam li ntawd, qhov txawv ntawm calcium atom thiab calcium ion yog dab tsi?
Piv txwv li, ib qho nruab nrab calcium atom , nrog 20 protons thiab 20 electrons, yooj yim poob ob electrons. Qhov no tshwm sim hauv cation nrog 20 protons, 18 electrons, thiab 2 + nqi. Lub npe hlau ion yog tib yam li lub npe ntawm cov hlau atom los ntawm uas nws tsim, yog li Ca2+ npe a calcium ion.
Tsis tas li ntawd, tus nqi ntawm calcium atom yog dab tsi? 2.
Xav txog qhov no, thaum calcium atom tsim ib ion Nws yog hu ua tus?
Yog ib atom poob electrons, lub ion tsim nyob rau hauv zoo nqi thiab hu ua ib cation. Txoj kev ua tiav yog: Ca2+ sawv cev ib ion nrog 20 protons thiab 18 electrons. A calcium atom muaj 20 protons thiab 20 electrons.
Tus nqi +2 txhais li cas?
Ions. Thaum lub atom nce lossis poob electrons, nws dhau los ua a raug nqi particle hu ua ion. Thaum ib qho atom tau txais electrons ntxiv, nws dhau los ua qhov tsis zoo raug nqi ion. Yog nws muaj tsuas yog ib qho ntxiv electron, nws fee yog -1. Yog hais tias nws tau txais ob lub electrons ntxiv, nws fee yog -2, thiab lwm yam.

Dab tsi yog electron configuration rau calcium atom?
[A] 4s²
Vim li cas carboxylate ion ruaj khov dua li Phenoxide ion?
Carboxylate ion ruaj khov dua li phenoxide ion. Qhov no yog vim hais tias nyob rau hauv phenoxide ion, tus nqi tsis zoo nyob rau ntawm ib qho electronegative oxygen atom thiab tsawg dua electronegative carbon atoms. Yog li ntawd lawv txoj kev koom tes rau resonance stabilization ntawm phenoxide ion tsawg dua
Thaum koj kub calcium carbonate ib qho khoom dawb nrog cov mis CaCO3 nws tawg los ua cov khoom calcium oxide CaO thiab carbon dioxide gas co2?
Thaum tshav kub kub tshaj 840 ° C, calcium carbonate decomposes, tso cov pa roj carbon dioxide thiab tawm hauv qab calcium oxide - cov khoom dawb. Calcium oxide hu ua txiv qaub thiab yog ib qho ntawm 10 cov tshuaj uas tsim tawm txhua xyoo los ntawm thermal decomposition ntawm limestone
Cov tshuaj tiv thaiv dab tsi yog calcium carbonate calcium oxide carbon dioxide?
Calcium carbonate tau kub siab kom txog thaum nws dhau los ua thermal decomposition los tsim calcium oxide thiab carbon dioxide. Cov calcium oxide (unslaked txiv qaub) yog yaj hauv dej los tsim calcium hydroxide (limewater). Bubbling carbon dioxide los ntawm qhov no ua ib qho kev ncua ntawm calcium carbonate
Yuav ua li cas yog qhov tshwm sim uas ib tug poj niam dig muag xim uas yuav ib tug txiv neej uas tsis pom kev zoo yuav muaj xim dig muag me nyuam?
Yog tias tus poj niam uas muaj lub zeem muag zoo li no (heterozygous rau qhov muag tsis pom xim) yuav ib tug txiv neej ib txwm muaj (XY), cov xeeb ceem hauv qab no tuaj yeem xav tau hauv F2 tiam: ntawm cov ntxhais, 50% yog ib txwm muaj thiab 50% yog cov neeg nqa khoom rau cov kab mob; ntawm cov tub, 50% yog xim dig muag thiab 50% yog qhov pom kev zoo
