7 daim ntawv cog lus
Ib yam li ntawd, fluorine puas tsim cov ntawv cog lus?
Nrog rau lwm cov atoms, fluorine cov ntaub ntawv ob polar covalent bonds los yog ionic daim ntawv cog lus . Feem ntau, covalent bonds koom nrog tshuaj fluorine atoms yog ib leeg daim ntawv cog lus , txawm tias tsawg kawg yog ob qho piv txwv ntawm kev txiav txim siab dua daim ntawv cog lus muaj.
Ib yam li ntawd, pes tsawg covalent daim ntawv cog lus zoo li muaj? peb covalent bonds
Dhau li ntawm no, koj yuav txiav txim siab pes tsawg covalent bonds ib lub caij muaj?
Tus naj npawb ntawm daim ntawv cog lus rau qhov nruab nrab atom yog sib npaug rau tus naj npawb ntawm electrons nyob rau hauv tag nrho valence plhaub (2 los yog 8electrons) rho tawm tus naj npawb ntawm valence electrons. Txoj kev no ua haujlwm vim txhua tus covalent bond tas ib atom cov ntaub ntawv ntxiv lwm cov hluav taws xob rau lub atoms valence plhaub yam tsis hloov nws cov nqi.
Puas yog covalent bonds muaj zog?
Covalent bonds kuj muaj nyob rau hauv inorganicmolecules zoo li H2O, CO2, thiab O2. Ib, ob, lossis peb khub ntawm electrons tuaj yeem sib koom, ua ib leeg, ob npaug, thiab triple daim ntawv cog lus , raws. Qhov ntau covalentbonds nruab nrab ntawm ob lub atom, lub muaj zog dua lawv kev sib txuas. Yog li, triple daim ntawv cog lus yog cov muaj zog tshaj.

Muaj pes tsawg protons neutrons thiab electrons 58 28ni muaj?
Ni-58 muaj atomic tooj ntawm 28 thiab ib tug loj tus naj npawb ntawm 58. Yog li ntawd, Ni-58 yuav muaj 28 protons, 28 electrons, thiab 58-28, los yog 30, neutrons.Ni-60 2+ hom, tus naj npawb ntawm Protons zoo ib yam li hauv nruab nrab Ni-58
Muaj pes tsawg atoms hauv cov duab molecule tuaj yeem tsim hydrogen bonds nrog dej?
Dr. Haxton hais rau nws cov chav kawm tias cov dej molecule tuaj yeem ua 4 hydrogen bonds, tag nrho lawv nyob rau hauv tib lub dav hlau raws li peb lub atoms
Hom kev sib cog lus twg yuav tsim ntawm fluorine thiab fluorine?
Electronegativity yog qhov txheeb ze. Thaum fluorine reacts nrog hlau, nws oxidizes hlau, thiab tsim ib daim ntawv cog lus ionic. Txawm li cas los xij, thaum ob lub fluorine atoms hnov mob los tsim cov fluorinemolecule, ib daim ntawv cog lus ntshiab yog tsim
Muaj pes tsawg guanine bases puas yog 50 lub hauv paus khub ob txoj hlua DNA 100 bases tag nrho muaj yog tias nws muaj 25 adenine bases?
Yog li, muaj tag nrho ntawm 25 + 25 = 50 adenine thiab thymine hauv tag nrho. Qhov ntawd tawm 100− 50 = 50 seem hauv paus. Nco ntsoov tias cytosine thiab guanine daim ntawv cog lus nrog ib leeg, thiab yog li lawv sib npaug ntawm cov nyiaj. Tam sim no peb tuaj yeem faib los ntawm 2 kom tau txais tus lej ntawm guanine lossis cytosine hauv paus
Muaj pes tsawg hom tshuaj lom neeg muaj pes tsawg leeg?
Hauv chaw ua haujlwm muaj ob hom kev phom sij: kev noj qab haus huv thiab kev phom sij ntawm lub cev
