Qhov no tin atom muaj 50 protons, 69 neutrons thiab 48 electrons.
Yog li ntawd, ua li cas koj thiaj nrhiav tau tus naj npawb ntawm cov electrons hauv ib qho atom uas tsis tau them?
Cov tus lej atomic sawv cev rau tus lej ntawm protons nyob rau hauv ib atom cov nucleus. Hauv ib uncharged atom , cov tus lej ntawm protons yeej ib txwm sib npaug rau cov tus naj npawb ntawm electrons . Piv txwv li, carbon atoms suav nrog rau protons thiab rau electrons , yog carbon tus lej atomic yog 6.
Ib sab saum toj no, muaj pes tsawg tus electrons nyob rau hauv ib qho atom ntawm lub caij 117? Xeev: Uncharged atoms muaj tib tus lej ntawm electrons raws li protons. Yuav ua li cas ntau electrons muaj nyob rau hauv ib tug uncharged atom ntawm lub caij 117 ? Cov keeb carbon muaj atomic tus naj npawb ntawm 6 vim nws muaj 6 protons. Nws cov isotope feem ntau muaj cov lej ntawm 12 vim nws muaj 6 neutrons ntxiv rau 6 protons.
Ib yam li ntawd, koj tuaj yeem nug, pes tsawg tus electrons nyob hauv atom ntawm tin?
2, 8, 18, 18, 4
Yog vim li cas ib tug atom uncharged?
Ib txwm atoms yog hluav taws xob tsis tau them nqi los yog nruab nrab. electrons, lawv coj tus nqi tsis zoo vim txhua tus atom tam sim no muaj ntau electrons tshaj protons. Ob qhov hluav taws xob zoo li qub thiab tam sim no tuaj yeem piav qhia los ntawm kev txav ntawm electrons los ntawm qhov tsis zoo atoms kom zoo them nqi atoms kom txog thaum muaj qhov sib npaug.

Tus naj npawb atomic sawv cev rau tus naj npawb ntawm protons hauv atom lub nucleus. Hauv ib qho atom uas tsis tau them nyiaj, tus naj npawb ntawm cov protons ib txwm sib npaug ntawm cov electrons. Piv txwv li, carbon atoms suav nrog rau protons thiab rau electrons, yog li cov pa roj carbon monoxide yog 6
Muaj pes tsawg electrons nyob rau hauv lub zog thib ob ntawm ib atom ntawm txhua lub caij?
Thaum thawj theem zog muaj 2 electrons, tom ntej no electrons mus rau theem ob lub zog mus txog rau theem thib ob muaj 8 electrons. Thaum lub zog thib ob muaj 8 electrons, tom ntej no electrons mus rau qib peb lub zog mus txog rau theem peb muaj 8 electrons
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
Muaj pes tsawg hom tshuaj lom neeg muaj pes tsawg leeg?
Hauv chaw ua haujlwm muaj ob hom kev phom sij: kev noj qab haus huv thiab kev phom sij ntawm lub cev
Yuav ua li cas muaj pes tsawg molecules ntawm carbon dioxide yog tsim thaum ib tug pyruvate molecule ua tiav los ntawm aerobic ua pa?
Lub yim kauj ruam ntawm lub voj voog yog cov tshuaj lom neeg cov tshuaj tiv thaiv uas ua rau cov hauv qab no los ntawm txhua qhov ntawm ob lub molecules ntawm pyruvate uas ua rau ib molecule ntawm qabzib uas tau pib mus rau hauv glycolysis (Daim duab 3): 2 carbon dioxide molecules. 1 ATP molecule (los yog sib npaug)
