Sidee si loo ogaado heerka uu qayilo

Dhammaan walxaha kiimikada ka kooban ee u taagoo, kuwaas oo ah qayb yar. Waxay koronto dhexdhexaad tahay oo ka kooban yihiin atamka, kuwaas oo lala by bonds covalent. awoodda atamka ee xubno ka kiimikada taagoo ah si ay u sameeyaan tiro gaar ah oo xiriir la yeedhay valence. In la xidhiidha bixitaanka iyo horumarinta aragtida ah silsilado kiimikada fikirkan uu maray isbedel weyn iyo hadda ma laha fasiraadda sayniska cad, inta badan loo isticmaalo ujeeddooyin waxbaridda iyo waxaa inta badan lagu tilmaamay heerka uu qayilo. Haddii Britain - waa wax ka walxaha yar, eb waa qayb qaybin karo element ugu yar kiimikada. Atom ayaa sidoo kale walxaha korontada dhexdhexaad ah in ay xarun uu leeyahay muhiimka ah ka kooban a protons togan ku amray, oo ku wareegsan waxaa jira daruur of electrons (xun eedeeyay). Sidaas daraaddeed taasu waxay dhacdaa dheelli amarka wanaagsan xuduntii amarka xun ee electrons. Si loo fahmo sida si loo ogaado heerka uu qayilo, iyo waxa ay tahay lagama maarmaan in la tixgeliyo dhismaha ee u taagoo of walxaha gaar ah.

In Britain ah chloride hydrogen (HCL) u dhexeeya hydrogen iyo chlorine, waxaa jira mid ka mid ah labada ciyaaryahan ee caanka ah ee electrons. eb hydrogen A ayaa ka mid ah proton iyo mid electron. eb chlorine 17 protons iyo electrons 17, mid ka mid ah toddobadii electrons in cufnaanta electron qolof dibadda Ciyaalle la electron ah la eb hydrogen si oon ku sameeyaan labada nin electron ah: H: cl. H2S The sameeyay Britain baaruud eb 2 labada ciyaaryahan la wadaago ee electrons labada atamka hydrogen: H: S: H. Sidee si loo ogaado heerka uu qayilo ee element ah, tusaale ahaan, chlorine iyo HCL ee hydrogen ee Britain iyo baaruud hydrogen in H2S Britain ee? Valency siinayaa fikrad ah lacagta la aasaasay xidhnahay Britain ama lammaane electron, laakiin ma muujiyaan in ay barakaca.

Waxaa la malaysan in electrons of atamka ee Britain ah lagu daro laba laba electron kuwaas oo u wareegeen eb ugu elekrootritsatelnomu ah. Hydrogen iyo chlorine in HCL ku bilaabi kartaa isgaarsiinta ah, kaas oo u wareegeen chlorine tan iyo waa ugu electronegative. Sayidka, heerka uu qayilo loo siman yahay si hydrogen oo lagu daray 1, halka chlorine - jaray 1. eb hydrogen kasta ee Britain ayaa ku H2S soo gala isgaarsiinta oo leh hal eb baaruud, taas oo iyana waxay leedahay laba silsilado. Labada kiiskan lammaane electron wareejiyay in ay la eb baaruud ah. Sidaa darteed, heerka uu qayilo ee lagu daray hydrogen u dhigmaa 1, iyo eb baaruudda - jaray 2. Sidee si loo ogaado heerka uu wakiilka qayilo, tus, HCL, H2S, O2, N2, Na, Ag, Si? qayilo walax fudud ama adag had iyo jeer waa 0, sida hubaasha ka kooban taagoo ama atamka iyo waxay koronto dhexdhexaad yihiin. Socota ka this, helidda heerka uu qayilo ee element ee Britain ayaa ku.

Tusaalaha of hypochlorous acid ka fiirsan kartaa sida si loo ogaado heerka uu qayilo, waayo, eb Champions League. In Britain HClO, sida in Britain walax kasta oo kale, hydrogen had iyo jeer waa (marka laga reebo hydrides) lagu gartaa qayilo oo lagu daray 1, iyo oxygen had iyo jeer waa - qayilo laga jaray 2 (waxaay sheegayaan barium iyo fluoride oxygen marka laga reebo). Maxaa yeelay, Britain waxay leedahay lacag la'aan laftiisa, waxaynu u qori karnaa isla'egta (1) + + x (- 2) = 0. isla'egta waa in la xalin: x = 0 - (1) - (-2) = (+1) sidaas, waxaa soo baxday in heerka uu qayilo ee Champions league per Britain ee lagu daray acid hypochlorous uyeelaysaan kuwo 1. tusaale ahaan tani waxay muujinaysaa sida si loo ogaado heerka uu qayilo ee element gaar ah ee Britain ah. First of dhan, qiyamka loo yaqaan waxaa lagu abaabulaa valency canaasiirta ama aan bedesho degree ee lagu qayilo.

Sayidka, qayilo waxaa loo yaqaan qiimaha shuruud (lacag rasmi ah oo la eb ee Britain ah) ee loo isticmaalo wax lagu qoro reactions isleegyo la xidhiidha lagu qayilo ama hoos u of walxaha kala duwan. Qiimaha Tani waxay la siman tirada lammaane oo electrons, kaas oo si buuxda u wareejiyay dhinaca taagoo electronegative xubno kiimikada. qayilo waxaa lagu diiwaangeliyaa badan la eb astaanta. entry Tani waxay muujinaysaa sida si loo ogaado heerka uu qayilo ee element gaar ah ee Britain ayaa ka mid ah wax kasta. Tusaale ahaan, rikoorka (Na + 1Cl-1) waa in la fahamsan yahay in Britain sodium heerka cusbo lagu qayilo oo lagu daray 1, oo laga jaray 1, iyo chlorine ku leeyahay, (+1) + (-1) = 0. In Britain ee -KP (K + 1Mn + 7O-24) oo lagu daray 1 potassium in manganese oo lagu daray 7, oksijiin ka jaray 2, waa in: (+1) + (+7) + 2 • (-2) = 0. Britain ee nitric acid (H + 1N + 5O-23) oo lagu daray 1 hydrogen, waayo, nitrogen lagu daray 5 oxygen ka jaray 2, iyo Britain oo dhan waa koronto dhexdhexaad ah: (+1) + (+5) + 3 • (-2) = 0. in Britain ay ka mid ah nitrus acid (H + 1N + 3o-22) oo lagu daray 1 hydrogen, waayo, nitrogen oo lagu daray 3 oxygen laga jaray 2, tan iyo amarka reer Britain waa loo siman yahay eber, markaas: (1) + (3) + 2 • (-2) = 0. Tusaale ahaan, nitrogen loo arki karaa in la eb this laga yaabaa in walxaha kala duwan ee gobolada kala duwan ee lagu qayilo daro ama laga jaro 3 ilaa 5 (la bareeg ah mid unit).
