Nto moo chemists: lub biography thiab achievements

Science News for KIDS - yog science hais tias rau ib ntev lub sij hawm mus ua hauj lwm rau cov neeg nyob rau hauv lawv cov niaj hnub xyaum ua. Qhov no kev qhuab qhia plays ib tug lossis loj lub luag hauj lwm nyob rau hauv niaj hnub kev lag luam, tsis muaj uas yuav tsis muaj nyob rau tib neeg kev vam meej. Tab sis xws li ib theem siab ntawm kev loj hlob nws twb tiav tsuas yog los ntawm tej hauj lwm ntawm zoo-paub zaum, uas mob siab rau nws lub neej mus rau Science News for KIDS.

Avogadro: kaw ntse heev

Ib qho ntawm feem tseem ceeb chemists yog Amedeo Avogadro. Nws yug los nyob rau hauv ltalis, nyob rau hauv lub tsev neeg official. Nyob rau hauv 1792, nws tau txais nws txoj cai kev kawm ntawv. Nws txiv kuj yog ib tug zoo-paub cov kws muaj txuj nyob rau hauv lub tshav pob ntawm kev cai lij choj. Pib ua hauj lwm nyob rau hauv lub PatientsÕ kheej, Avogadro nyob rau hauv nws lub sij hawm dawb koom nyob rau hauv txoj kev tshawb no ntawm physics thiab kev kawm zauv. Tsuas yog nyob rau hauv 1820 nws tau txais lub npe ntawm cov xibfwb ntawm lub cev thiab lej Sciences.

Nto moo chemists thaum lub sij hawm uas sau hais tias Avogadro yog ib tug heev reserved txiv neej, yog li muaj ntau yam ntawm nws lub tswv yim twb tsis meej rau lawv. Recognition nyob rau hauv scientific voj voog Avogadro tau txais tom qab kabke ntawm nws nto moo kev tshawb xav, tom qab lub npe hu ua "Avogadro txoj cai". Avogadro tseg tus naj npawb ntawm cov neeg uas muaj ntau cov tshuaj hais, nws tau tsim ib tug qauv rau kev txiav txim lub molecular ceeb thawj.

Biography thiab kev tshawb fawb kev txaus siab Boyle

Tseem ceeb luag hauj lwm nyob rau hauv txoj kev loj hlob ntawm Science News for KIDS ua si thiab achievements Roberta Boylya. Nws yug los lub ib hlis ntuj 25, 1627 nyob rau hauv Ireland. Raws li ib tug me nyuam, nws twb kawm ntawv nyob rau hauv tsev, thiab ces twb raug xa mus Eton School, qhia tshwj xeeb uas tsim rau cov me nyuam ntawm muaj myiaj aristocrats. Nyob rau hauv 1656 Robert Boyle tsiv mus rau Oxford, qhov uas nws pib mus rau manifest nws tus paj laum nyob rau hauv physics thiab Science News for KIDS. Muaj Boyle tsim phooj ywg kev sib raug zoo nrog addicted rau science los ntawm cov kws tshawb fawb. Ua ke lawv tau tsim ib tug zoo ntawm daim card haiv neeg, uas tom qab ua lub Oxford tshawb fawb Society.

Nto moo chemists thaum lub sij hawm yuav paub tseeb tias Boyle tsis nyiam controversy, thiab zam txawm lub scientific controversy uas feem ntau coj qhws ib tug humorous cim. Boyle tsim tswvyim ntawm tus thiaj li hu ua "tus thawj kws corpuscles" (basic hlwb) thiab "theem nrab corpuscles (complex lub cev). Nyob rau hauv nws phau ntawv hu ua "Lub skeptical chemist" Boyle rau thawj lub sij hawm lub sij lub ntsiab - "tus thawj lub cev, uas yog tsis twv tawm ntawm txhua lwm yam." Nyob rau hauv tas li ntawd mus Science News for KIDS, Boyle txoj kev tshawb fawb teem rau qhov chaw ntawm optics, acoustics thiab hluav taws xob.

kev tshawb fawb Werner

Alfred Werner yug rau lub Kaum Ob Hlis 12, 1866 nyob rau hauv lub Turner tsev neeg. Tom qab kawm tiav rau xyoo los ntawm lub tsev kawm ntawv elementary Werner nkag mus rau hauv Technical School thiab yog xav nyob rau hauv Science News for KIDS. Nws pib muab tshuaj thwmsim txoj cai nyob rau hauv tsev. Nyob rau hauv tas li ntawd, tus tub hluas paub txog xav nyob rau hauv cov ntaub ntawv thiab txawm architecture. Chemist Alfred Werner twb muab tsub lub Nobel nqi zog rau nws authorship ntawm lub thiaj li hu ua kev sib koom tes hauv kev tshawb xav. Nyob rau hauv tas li ntawd, Werner tau tsim nws tus kheej lub hom phiaj ntawm acids thiab bases, thiab muaj nws tus kheej version ntawm lub Periodic rooj. Nyob rau hauv 1913 nws tau txais lub Nobel nqi zog.

Achievements Niels Bohr nyob rau hauv Chemistry

Nto moo chemists tag nrho cov thoob lub ntiaj teb no mus hnub no txaus siab rau cov tau ntawm Niels Bohr, uas tau lom zem ntau lub npe hu rau nws kev tshawb fawb nyob rau hauv lub teb ntawm physics. Niels Bohr tsim quantum kev tshawb xav hydrogen atom. Nyob rau hauv nws, nws piav qhia nta kev sib hloov electrons thiab lej piav tej lub xeev ntawm lub atom.

Niels Bohr yug Lub kaum hli ntuj 7, 1885 nyob rau hauv Copenhagen, nyob rau hauv ib tug kev txawj ntse tsev neeg. Nyob rau hauv lub tsev ntawm nws niam nws txiv twb feem ntau muaj nyob rau cov kev sib tham nyob rau hauv cov tshuaj pleev scientific teeb meem. Thaum kawm nyob rau hauv lub University of Copenhagen Bohr tau txais cov puav pheej ntawm cov Danish Academy ntawm Sciences. Lwm yam paub chemists - mas Ernest Rutherford - twb kawm Bohr lus nug radioactivity ntsiab thiab atomic qauv.

Svante Arrhenius - chemist los ntawm Sweden

Lwm tseem ceeb soj ntsuam nyob rau hauv lub tshav pob ntawm Science News for KIDS - Svante Arrhenius. Nws yug los Lub ob hlis ntuj 19, 1859 nyob rau hauv Uppsala. Nyob rau hauv 1876 nws cuv npe kawm nyob rau hauv lub University, thiab rau lub hlis ua ntej tau txais ib tug degree nyob rau hauv Philosophy. Txij li thaum 1881 Arrhenius pib txoj kev tshawb no ntawm aqueous lub ntsiab ntawm electrolytes nyob rau hauv Stockholm lub koom haum ntawm Physics. Nyob rau hauv 1903, tus paub txog twb muab tsub lub Nobel nqi zog rau cov neeg sau ntawm lub hom phiaj ntawm electrolytic dissociation.

Nws yog lub npe hu hais tias Arrhenius muaj ib tug zoo-natured thiab muaj lus zoo siab ua cim. Thaum lub sij hawm, nws twb paub tsis tau tsuas yog raws li ib tug kws ntawv tab sis kuj raws li cov neeg sau ntawm cov phau ntawv thiab cov khoom nyob rau astronomy thiab tshuaj. Zaum tau ntev pom tau hais tias cov Science News for KIDS ntawm nws ua tau: Piv txwv, nws theories tau sharply criticized los ntawm Mendeleev. Tom qab ntawd nws muab tawm hais tias cov views ntawm ob soj ntsuam ua lub hauv paus ntawm lub tshiab, yog li ntawd-hu ua proton, kev tshawb xav bases nyob rau hauv Science News for KIDS.
