Gome lathunthu la atomiki la mankhwala ndi malangizo ofulumira a mnemonic

Kulowa giredi 8, ophunzira ayamba kuzolowera Chemistry. Pamodzi ndi chidziwitso choyambirira monga tebulo la valency, tebulo la atomiki la chemistry lidzakutsatani panthawi yonse yophunzirira chemistry ndipo ndi chida chothandizira kuthana ndi mavuto a chemistry mwamsanga. Gawani nkhani yotsatira kuti muloweze tebulo la atomiki mwachangu!

I. KODI PHIRI NDI CHIYANI CHOKHALAPO?

1. Kodi misa ya atomiki ndi chiyani?

Mukuwona: Tebulo lathunthu la chemistry atomic mass ndi malangizo ofulumira a mnemonic

Unyinji wa atomiki wa atomu ndi kuchuluka kwa atomu ya chinthucho, chomwe ndi kuchuluka kwa ma elekitironi, ma protoni, ndi ma neutroni, koma chifukwa misa ya ma elekitironi ndi yaying’ono kwambiri nthawi zambiri samawerengedwa, kotero ndizotheka. kuti chiwerengero cha atomu chiŵerengero cha kernel.

Mukuwona: Table dvc

Kapena mophweka:

Misa ya atomiki ndi kuchuluka kwa atomu mu mayunitsi a carbon. Zinthu zosiyanasiyana zimakhala ndi ma atomu osiyanasiyana.

Mwachitsanzo: Atomic mass of Nitrogen (N) = 14 (dvC), ya Magnesium (Mg) = 24 (dvC).

2. Misa ya Atomiki

Atomic mass unit ndi gawo la misa kwa unyinji wa ma atomu ndi mamolekyu. Nthawi zambiri imakhala yofanana ndi gawo limodzi mwa magawo khumi ndi awiri a unyinji wa atomu ya kaboni 12. Chifukwa chake, gawo la misa ya atomiki limadziwikanso kuti gawo la kaboni, lotchedwa dvC.

3. Avereji ya kulemera kwa atomiki

Zinthu zambiri zama mankhwala ndi zosakaniza za isotopu zambiri zokhala ndi ma atomu ambiri => kuchuluka kwa ma atomiki azinthu okhala ndi isotopu ambiri ndi kuchuluka kwa ma atomiki osakanikirana ndi isotopu okhala ndi ma isotopu osiyanasiyana.

4. Kodi gawo la misa ya atomiki ndi chiyani?

Mpweya wa Carbon ndi gawo lomwe limagwiritsidwa ntchito kuyeza kulemera kwa atomu, ndi chizindikiro cha unit C. Mpweya umodzi wa carbon ndi wofanana ndi 1/12 wa unyinji wa nyukiliyasi ya atomiki ya isotopu carbon C12.

Chifukwa atomu ya kaboni ndi isotopu wamba C12 ndipo index yolakwika ndiyotsika kwambiri, bungwe la International Metrology Institute lavomera kugwiritsa ntchito gawoli la kaboni.

II. ZINTHU ZONSE ZA CHEMICAL ZINTHU ZOKHUDZA

Zotsatirazi ndi tebulo lathunthu lowerengera la monochemistry lomwe lili ndi zinthu zopitilira 100 zomwe zimagwiritsidwa ntchito komanso zosowa.

1.Nthawi zonse chitani chemistry homework

Iyi ndiye njira yabwino kwambiri yoloweza pamtima pa tebulo la atomiki. Mukamvetsetsa zapakati pa zomwe zili muphunziro lake mwachangu. Ndipo mutatha kuloweza mafomuwa, muyenera kuyeseza pafupipafupi, nthawi zina muyenera kubwerezanso kuti musaiwale.

2. Phunzirani kupyolera mu nyimbo ya atomiki

Pakakhala nyimbo zokhuza atomu yamankhwala awa, zimakhala zosavuta kuloweza komanso kuloweza. Nazi nyimbo 2 zosaiŵalika za ma atomiki. Chonde onani!

1. Pezani zinthu mu kompositi:

Kwa masitepe oyamba mu chemistry, iyi ndi imodzi mwamitundu yodziwika bwino yamaphunziro. Nachi chitsanzo chosavuta:

Kuphatikizika kwachitsulo A kuphatikiza ndi asidi H2SO4″>H2SO4H2SO4 kupanga mchere wokhala ndi chilinganizo ASO4″>ASO4ASO4. Mamolekyu onse a pawiriwa ndi mayunitsi 160. Dziwani chinthu A.

Onaninso: Kuthetsa Mavuto a Masamu 8 Kuthetsa Mavuto a Masamu Popanga ma Equations

Titha kuthetsa vutoli mosavuta motere:

Pa tebulo la misa ya atomiki tikuwona

Kulemera kwa atomiki S ndi :32

Kuchuluka kwa atomiki wa oxygen ndi :16

Malinga ndi formula yapawiri, tili ndi A+32+16×4=160

2. Pezani chinthu pamene misa ya atomiki imadziwika

Pazochita zosavuta zosankha zingapo mugiredi 8, nthawi zambiri mumakumana ndi mafunso ngati

Dziwani chinthu chomwe kulemera kwake kwa atomiki kuwirikiza kawiri kuposa okosijeni Kuti muchite izi, muyenera kudziwa kuti misa ya atomiki ya okosijeni ndi 16, chinthu chomwe chili ndi mphamvu ya atomiki ya 2 nthawi ya okosijeni imakhala ndi ma atomiki a 32. Monga mukuonera, yankho la funsoli ndi sulfure. Chifukwa chake takubweretserani tebulo lathunthu la chemistry yayikulu ya atomiki ndi malangizo ofulumira a mnemonic. Tikukhulupirira, mutagawana nkhani yomweyi, mwadziwa bwino gawo ili lachidziwitso.
