Atoms tau created tom qab lub Big Bang 13.7 billion xyoo dhau los. Raws li qhov kub, ntom tshiab ntug txias, cov xwm txheej tau tsim nyog rau quarks thiab electrons los ua. Quarks tuaj ua ke los tsim cov protons thiab neutrons, thiab cov khoom no ua ke rau hauv nuclei.
Leej twg tsim atoms?
Lub tswv yim hais tias txhua yam yog ua los ntawm atoms yog pioneered los ntawm John D alton (1766-1844) nyob rau hauv ib phau ntawv nws luam tawm nyob rau hauv 1808. Tej zaum nws yog hu ua "txiv" ntawm atomic txoj kev xav, tab sis txiav txim los ntawm daim duab no ntawm txoj cai "txiv yawg" tej zaum yuav yog lub ntsiab lus zoo dua.
Puas atoms raug tsim?
Cov lus teb luv luv yog yog, atoms raug tsim txhua lub sijhawm… Nws yog hu ua nuclear fusion thiab pib koom nrog kev sib xyaw protons thiab neutrons ua ke los tsim cov atoms tshiab - qee cov hydrogen, Qee qhov helium, qee qhov lithium, thiab lwm yam, txhua txoj kev mus rau hlau. Lwm txoj hauv kev los ua cov atom tshiab yog los ntawm supernova.
Atom thawj zaug tshwm sim li cas?
thawj cov pov thawj niaj hnub rau atoms tshwm sim thaum ntxov 1800s thaum Askiv chemist John D alton nrhiav pom tias cov tshuaj ib txwm muaj tag nrho cov lej ntawm atoms.
Pob atoms ib txwm muaj nyob?
Protons, neutrons, thiab electrons nyob ib puag ncig lawv yog qhov ntev- cov khoom nyob hauv txhua qhov zoo tib yam, ib txwm tshwm sim atoms. Lwm cov subatomic particles yuav pom nyob rau hauv koom nrog peb hom hais. … Tag nrho cov atoms yog kwv yees li qhov loj me, txawm tias lawv muaj 3 lossis 90 electrons.
