Atoms muaj peb yam yooj yim hais: protons, electrons, thiab neutrons. Lub nucleus (center) ntawm lub atom muaj cov protons (zoo them) thiab cov neutrons (tsis muaj nqi). Outermost cheeb tsam ntawm lub atom hu ua electron shells thiab muaj cov electrons (negatively charged).
Nyob rau hauv txoj kev no, dab tsi yog cov yam ntxwv ntawm electron?
Hluav taws xob yog cov tsis zoo them nqi ntawm atom. Ua ke, tag nrho cov electrons ntawm ib qho atom tsim cov nqi tsis zoo uas sib npaug qhov zoo ntawm cov protons hauv atomic nucleus. Hluav taws xob yog me me heev piv rau tag nrho lwm qhov ntawm lub atom.
Ib yam li ntawd, cov yam ntxwv ntawm neutrons yog dab tsi? Neutron , nruab nrab subatomic particle uas yog ib feem ntawm txhua atomic nucleus tsuas yog hydrogen zoo tib yam. Nws tsis muaj nqi hluav taws xob thiab qhov seem loj sib npaug rau 1.67493 × 10−27 kg-marginally ntau dua li ntawm cov proton tab sis ze li ntawm 1,839 npaug ntau dua li ntawm cov electron.
Raws li, 4 yam khoom ntawm lub atom yog dab tsi?
- Qhov ntau thiab tsawg ntawm atom thiab nucleus.
- Feem ntau ntawm atom qhov loj yog nyob rau hauv lub nucleus.
- Cov khoom xyaw: protons, neutrons, electrons.
- Lub zog hluav taws xob tuav atom ua ke.
- Nuclear quab yuam tuav nucleus ua ke.
- Atoms, ions.
- Atomic naj npawb.
Dab tsi yog tus yam ntxwv ntawm atom Brainly?
Atoms yog cov khoom siv tsawg tshaj plaws ntawm cov teeb meem thiab lawv muaj cov khoom siv tshuaj lom neeg. Atoms tsis tuaj yeem tawg los ntawm kev siv tshuaj lom neeg. Atoms ntawm cov khoom sib xyaw ua ke los tsim cov khoom sib xyaw. Ntxiv rau atoms muaj cov nucleus ntawm qhov zoo them protons, nruab nrab neutrons nrog cov electrons tsis zoo.

Cov yam ntxwv ntawm lub cev dab tsi yog siv los txhais cov biomes?
Kub thiab nag lossis daus, thiab kev hloov pauv hauv ob qho tib si, yog qhov tseem ceeb ntawm cov kab mob abiotic uas ua rau muaj cov tsiaj txhu thiab cov nroj tsuag hauv zej zog hauv av biomes. Qee cov biomes, xws li cov nyom nyom thiab hav zoov kub, muaj lub caij sib txawv, nrog rau huab cua txias thiab huab cua kub hloov pauv txhua xyoo
Yam dab tsi ua rau cov yam ntxwv ntawm lub ntiaj teb muab piv txwv?
Biotic thiab abiotic factor Biotic yam muaj xws li tsiaj txhu, nroj tsuag, fungi, kab mob, thiab protists. Qee qhov piv txwv ntawm abiotic yam yog dej, av, huab cua, hnub ci, kub, thiab cov zaub mov
Dab tsi yog qhov txawv ntawm Marine West Coast huab cua thiab dab tsi yog lub luag haujlwm rau cov yam ntxwv ntawd?
Cov ntsiab lus ntawm Marine West Coast Qhov kev nyab xeeb ntawm cov yam ntxwv tseem ceeb yog lub caij ntuj sov me me thiab lub caij ntuj no thiab cov nag lossis daus txhua xyoo. Qhov ecosystem no muaj kev cuam tshuam loj heev los ntawm nws qhov ze rau ntawm ntug dej hiav txwv thiab roob. Nws yog qee zaum hu ua huab cua sab hnub poob ntug dej hiav txwv lossis dej hiav txwv huab cua
Dab tsi ntawm lub cev nta yog cov yam ntxwv ntawm cov ntug dej hiav txwv ntawm Texas?
Texas 'Gulf Coastal Plains yog sab hnub poob txuas ntxiv ntawm ntug hiav txwv tiaj tiaj txuas los ntawm Dej Hiav Txwv Atlantic mus dhau Rio Grande. Nws cov yam ntxwv dov mus rau toj roob hauv pes npog nrog kev loj hlob hnyav ntawm ntoo thuv thiab tawv ntoo txuas mus rau East Texas
Peb lub neej yog dab tsi thiab lawv cov yam ntxwv tshwj xeeb yog dab tsi?
Peb lub npe suav nrog: Archaea - cov npe qub tshaj plaws, cov kab mob qub. Cov kab mob - tag nrho lwm cov kab mob uas tsis suav nrog hauv Archaea domain. Eukarya - tag nrho cov kab mob uas muaj eukaryotic los yog muaj cov kab mob sib txuas thiab cov nuclei
