Plutonium muaj ntau ntau nyob rau hauv lub ntiaj teb txij li thaum 1945 raws li ib yam khoom ntawm neutron capture thiab beta lwj, qhov twg ib co ntawm cov neutrons tso tawm los ntawm lub fission txheej txheem hloov. uranium -238 nuclei ua plutonium -239.

Tom qab ntawd, cov ntsiab lus dab tsi uas plutonium hnov mob nrog?
Plutonium yog chemically reactive. Nws tarnishes hauv huab cua , noj nyob rau hauv ib tug daj cam khwb cia thaum oxidized. Nws dissolves nyob rau hauv hydrochloric, hydriodic, thiab perchloric acids thiab reacts nrog halogens, carbon , nitrogen , thiab silicon . Cov hlau ntshiab plutonium tuaj yeem npaj los ntawm kev txo cov trifluoride, PuF 3, nrog calcium hlau.
Tsis tas li ntawd, plutonium nyob qhov twg ntawm lub rooj zaum? Plutonium . Plutonium yog ib tug tswv cuab ntawm pawg actinide nyob rau hauv lub daim ntawv qhia hnub . Plutonium atoms muaj 94 electrons thiab 94 protons nrog 2 valence electrons nyob rau hauv lub plhaub txheej. Muaj 150 neutrons nyob rau hauv cov isotope ntau tshaj.
Tsis tas li ntawd, puas yog plutonium ntawm lub rooj zaum?
Plutonium (Pu), hluav taws xob chemical keeb ntawm cov actinoid series ntawm cov daim ntawv qhia hnub , atomic nr 94.
Puas yog plutonium yog qhov hnyav tshaj plaws tshwm sim?
Muaj 91 ib txwm tshwm sim cov ntsiab lus (tab sis nws nyob ntawm seb koj suav lawv li cas). Cov hnyav tshaj plaws uas tshwm sim nyob rau hauv loj yog uranium (atomic tooj 92). Promethium (atomic tooj 61) tsis tshwm sim ib txwm . Plutonium -244 (244Pu) tau pom nyob rau hauv qhov xwm txheej!

Lub ntsiab lus ntawm lub hauv paus lo lus meter nyob rau hauv lo lus tus pas ntsuas kub yog dab tsi?
Lub hauv paus chiv keeb ntawm lo lus 'Thermometer' Qhov thib ob ntawm lo lus, 'meter', los ntawm Fabkis -mètre (uas muaj nws cov hauv paus hauv lub post-classical Latin: -meter, -metrumand lub ancient Greek, -Μέτρο ν, lossis metron, uas txhais tau tias ntsuas qee yam, xws li qhov ntev, qhov hnyav, lossis dav)
Lub ntsiab lus twg yog pom nyob rau hauv qhov tsuas yog nyob rau hauv tebchaw quizlet?
Halogens yeej ib txwm pom nyob rau hauv cov xwm txheej incompounds vim hais tias halogens yog heev reactivenonmetals
Thaum twg Mendeleev tau teeb tsa cov ntsiab lus hauv lawv lub sijhawm teem sijhawm?
1869 Ntxiv mus, qhov kev txiav txim dab tsi Mendeleev npaj cov ntsiab lus nyob rau hauv lub sij hawm? Kev piav qhia: Mendeleev yuam nws cov ntsiab lus hauv nws daim ntawv qhia hnub hauv xaj ntawm atomic mass. Qhov nws pom los ntawm qhov no yog qhov zoo sib xws cov ntsiab lus tau pab pawg ua ke.
Puas yog cov ntsiab lus uas muaj cov tshuaj lom neeg zoo sib xws yuav pom nyob rau tib lub sijhawm lossis hauv tib pab pawg piav qhia koj cov lus teb?
Qhov no yog vim hais tias cov tshuaj muaj zog nyob ntawm tsis muaj valence electrons. Raws li nyob rau hauv ib pawg tag nrho cov ntsiab lus muaj tib yam tsis muaj valence electron uas yog vim li cas lawv muaj cov tshuaj zoo sib xws tab sis nyob rau hauv ib lub sij hawm tsis muaj valence electron sib txawv uas yog vim li cas lawv txawv nyob rau hauv chemical zog
