Nuclear Notation
Rau Lub Sij Hawm Lub Sij Hawm, Tus lej Atomic yog nyob rau sab saum toj thiab qhov nruab nrab atomic loj nyob hauv qab. Rau Nuclear daim ntawv , tus lej ntawm cov isotope mus rau sab saum toj thiab tus lej atomic mus rau hauv qab.
Ib yam li ntawd, lub ntsiab lus nuclear yog dab tsi?
Nuclear Notation . Txuj Nuclear daim ntawv qhia cov tshuaj cim , tus lej loj thiab tus lej atomic ntawm isotope. Lub caij yog txiav txim los ntawm tus lej atomic 6. Carbon-12 yog cov isotope uas muaj, nrog carbon-13 yog lwm cov isotope ruaj khov uas ua rau li 1%.
Tsis tas li ntawd, puas yog protons thiab electrons tib yam? Tiag tiag cov proton thiab electron suav ntawm atom yog sib npaug tsuas yog thaum lub atom yog nruab nrab nyob rau hauv tus nqi. Peb lub atomic particles ntawm ib lub atom yog cov protons , uas nqa ib tug zoo nqi, lub electrons uas nqa tus nqi tsis zoo thiab cov neutrons uas tsis muaj nqi.
Tsis tas li lo lus nug yog, ua li cas koj sau helium hauv cov cim cim?
Rau sau ua tiav nuclear cim , tus lej loj yog muab tso rau ntawm sab laug sab sauv (superscript) ntawm cov tshuaj cim thiab tus lej atomic tau muab tso rau ntawm sab laug sab laug (subscript) ntawm cim . Ua tiav nuclear cim rau helium egin{align*}-4end{align*} yog kos hauv qab no.
Lub cim isotope yog dab tsi?
Isotope notation, tseem hu ua nuclear notation, yog ib qho tseem ceeb vim hais tias nws tso cai rau peb siv qhov muag pom cim kom yooj yim txiav txim siab ib cov isotope loj naj npawb, atomic tooj, thiab txiav txim seb tus naj npawb ntawm neutrons thiab protons nyob rau hauv lub nucleus tsis tas yuav siv ntau lo lus. Tsis tas li ntawd, N = A-Z.

Vim li cas koj thiaj siv cov ntawv sau ua haujlwm?
Function notation yog ib txoj hauv kev los sau cov haujlwm uas yooj yim nyeem thiab nkag siab. Kev ua haujlwm muaj qhov sib txawv thiab muaj kev ywj pheej, thiab thaum peb siv cov cim kev ua haujlwm, qhov kev hloov pauv ywj pheej feem ntau yog x, thiab qhov sib txawv ntawm qhov sib txawv yog F (x). Function notation yog ib txoj kev sib txawv ntawm kev sau ntawv kev sib raug zoo, ok
Txoj kev faib cov ntaub ntawv twg muab cov ntaub ntawv sib npaug ntawm cov ntaub ntawv lossis cov kev tshuaj xyuas hauv txhua chav kawm cov ntaub ntawv?
Quantile. txhua chav kawm muaj cov yam ntxwv sib npaug. Ib qho kev faib tawm ntau yog zoo haum rau cov ntaub ntawv faib tawm. Quantile muab tib tus lej ntawm cov ntaub ntawv muaj nuj nqis rau txhua chav kawm
Koj sau Ap Lang sau ntawv li cas?
Synthesis Writing Dos and Don'ts DO Tsim kom muaj zog, Clear Thesis Statement. TSIS siv cov kab lus. Cite koj cov peev txheej kom raug thiab tsim nyog. DO Sketch a Basic Outline. UA Pace Koj tus kheej. Ua pov thawj thiab kho koj cov ntawv sau ua tib zoo
Koj puas siv cov lus qhia hauv kev sau ntawv sau?
Tsab ntawv no yog ntsuas koj lub peev xwm los tsim qhov kev sib cav uas siv cov peev txheej. Yog tias koj siv cov ntaub ntawv los ntawm cov peev txheej, koj yuav tsum sau nws. Yog tias koj nqa cov ntawv tawm ntawm qhov chaw, koj yuav tsum muab tso rau hauv cov lus hais. Tom qab koj hais los yog piav ib qhov chaw, hais nws raws li koj xav tau hauv ib daim ntawv: (Source F) lossis (Gilman)
Yuav ua li cas koj sau txoj kab nqes nqes intercept daim ntawv nyob rau hauv tus qauv daim ntawv?
Standard form yog lwm txoj hauv kev los sau daim ntawv nqes hav-intercept (as opposed to y=mx+b). Nws sau li Ax+By=C. Koj tuaj yeem hloov daim ntawv nqes hav-intercept rau cov qauv zoo li no: Y=-3/2x + 3. Tom ntej no, koj cais qhov y-intercept (qhov no nws yog 2) zoo li no: Ntxiv 3/2x rau txhua sab ntawm kab zauv kom tau qhov no: 3/2x + y = 3
