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!
