Tsis tas li ntawd, pes tsawg neutrons nickel muaj?
31 neutron
Qhov thib ob, koj yuav nrhiav tau tus lej loj li cas? Ua ke, lub tus lej ntawm cov protons thiab tus lej ntawm neutrons txiav txim siab lub ntsiab pawg naj npawb : pawg naj npawb = protons + neutrons. Yog tias koj xav suav pes tsawg neutrons ib lub atom muaj, koj tuaj yeem rho tawm qhov yooj yim tus lej ntawm protons, los yog atomic tus lej , los ntawm pawg naj npawb.
Ib sab saum toj, dab tsi yog Bohr qauv ntawm nickel?
Ib qho ruaj khov npib tsib xee atom muaj 28 protons, 28 electrons, thiab 31 neutrons. Cov electrons ntab ncig lub nucleus hauv qhov chaw thiab qhov no muaj 28 ntawm lawv. Cov hluav taws xob tsawg heev uas lawv tsis muaj qhov hnyav hauv ib lub atom. Kuv txhais tes kos qauv yog nyob rau sab saum toj thiab lwm yam Bohr qauv ntawm a npib tsib xee atom yog nyob rau hauv qab.
Nickel nrhiav tau qhov twg?
Nws kuj yog pom nyob rau hauv lub ntiaj teb lub crust qhov twg nws yog hais txog nees nkaum-ob feem ntau cov khoom. Feem ntau npib tsib xee uas yog mined rau industrial siv yog pom nyob rau hauv ores xws li pentlandite, garnierite, thiab limonite. Cov neeg tsim khoom loj tshaj plaws ntawm npib tsib xee yog Russia, Canada, thiab Australia.

Dab tsi yog qhov txawv ntawm qhov pom tseeb qhov loj thiab qhov ntsuas qhov ntsuas qhov tseeb?
Dab tsi yog qhov txawv ntawm qhov pom tseeb thiab qhov tseeb? Pom meej qhov loj npaum li cas yog qhov ci ntawm lub hnub qub tshwm los ntawm lub ntiaj teb thiab nyob ntawm qhov ci thiab qhov deb ntawm lub hnub qub. Qhov loj npaum li cas yog qhov ci ntawm lub hnub qub yuav tshwm sim los ntawm tus qauv nyob deb
Qhov txawv ntawm qhov loj ntawm ib tug proton thiab qhov loj ntawm ib tug electron yog dab tsi?
Protons thiab neutrons muaj kwv yees li qub, tab sis lawv yog ob qho tib si loj dua li cov hluav taws xob (kwv yees li 2,000 npaug loj li electron). Tus nqi zoo ntawm ib qho proton yog sib npaug hauv qhov loj rau qhov tsis zoo ntawm tus electron
Dab tsi yog qhov txawv ntawm nickel plating thiab electroless nickel plating?
A. Electrolytic npib tsib xee yog tso siv DC tam sim no, thaum Electroless Ni yog autocatalytic deposition. Electroless Ni ua rau plating ntawm cov tuab tuab thoob plaws hauv ib feem, thaum electrolytic Ni daim hlau ua kom tuab dua nyob rau hauv qhov chaw siab tam sim no
Dab tsi yog qhov yuam kev loj tshaj plaws yog tias Irina ntsuas qhov ntev ntawm nws lub qhov rais li 3.35 feet qhov yuam kev loj tshaj plaws yog taw?
Kev daws: Qhov yuam kev loj tshaj plaws hauv kev ntsuas ntsuas tau txhais tias yog ib nrab ntawm qhov ntsuas ntsuas
Dab tsi yog qhov txawv ntawm instantaneous thiab nruab nrab ceev dab tsi yog qhov piv txwv loj tshaj ntawm kev ceev ceev?
Qhov nruab nrab ceev yog qhov ceev nruab nrab ntawm lub sijhawm. Instantaneous ceev yuav yog qhov ceev txhua qhov muab tam sim ntawd hauv lub sijhawm ntawd, ntsuas nrog lub ntsuas ntsuas lub sijhawm
