Tus naj npawb ntawm electrons nyob rau hauv lub plhaub sab nraud ntawm ib lub atom txiav txim nws reactivity . Noble gases muaj tsawg reactivity vim lawv muaj tag nrho cov electron plhaub. Halogen muaj ntau heev reactive vim lawv tau txais ib qho hluav taws xob los sau lawv lub plhaub sab nraud.
Ib yam li ntawd, koj yuav ua li cas thiaj paub tias lub ntsiab lus twg muaj ntau dua reactive?
Cov cov ntsiab lus mus rau hauv qab sab laug ces kaum ntawm lub periodic rooj yog cov hlau uas yog cov feem ntau active nyob rau hauv lub siab ntawm ua tus feem ntau reactive . Piv txwv li, lithium, sodium, thiab poov tshuaj tag nrho react nrog dej.
Ib sab saum toj no, dab tsi yog qhov sib txawv hauv kev ua haujlwm ntawm lub rooj zaum? Qhov deb mus rau sab laug thiab nqes daim ntawv qhia caij nyoog koj mus, qhov yooj yim dua nws yog rau electrons muab los yog muab tshem tawm, ua rau siab dua reactivity . Lub sijhawm - reactivity nce thaum koj mus ntawm sab laug mus rau sab xis hla ib lub sijhawm. Pab pawg - reactivity txo qis thaum koj mus rau pawg.
Tib neeg kuj nug, ua li cas valence electrons txiav txim siab reactivity?
Valence electrons yog tus naj npawb ntawm electrons nyob rau hauv lub atoms sab nraum lub plhaub. Qhov ntau los yog tsawg valence electrons nws muaj (piv txwv li 1 thiab 7, muaj ze rau lub plhaub sab nraud ua rau nws ntau dua reactive ) tuaj yeem ua rau lub atom ntau dua lossis tsawg dua reactive . (tsawg reactive atoms xws li atoms nrog 4 lossis 8 valence electrons ).
Qhov twg reactivity nce?
Cov no tshwm sim los ntawm poob electrons thiab reactivity nce raws li koj mus rau pawg. Qhov no yog vim cov nce Tus naj npawb ntawm cov plhaub hluav taws xob ua rau muaj kev tiv thaiv ntau dua thiab qhov kev ncua deb ntawm cov hluav taws xob sab nraud thiab cov nucleus, uas txo cov kev nyiam ntawm cov electrons mus rau lub nucleus.

Yuav ua li cas koj txiav txim siab yog hais tias ib tug muaj nuj nqi muaj ib tug kab rov tav tangent?
Kab rov tav kab muaj txoj kab nqes ntawm xoom. Yog li ntawd, thaum lub derivative yog xoom, cov kab tangent yog kab rov tav. Txhawm rau nrhiav cov kab kab rov tav tangent, siv qhov derivative ntawm txoj haujlwm los nrhiav qhov xoom thiab ntsaws lawv rov qab rau hauv qhov sib npaug qub
Koj yuav txiav txim siab li cas yog tias kev sib raug zoo yog qhov ua haujlwm ntawm daim duab?
LUS TEB: Cov lus teb piv txwv: Koj tuaj yeem txiav txim siab seb txhua lub ntsiab lus ntawm lub npe yog ua ke nrog ib lub ntsiab lus ntawm qhov ntau. Piv txwv li, yog muab ib daim duab, koj tuaj yeem siv txoj kab ntsug; Yog hais tias ib txoj kab ntsug hla cov duab ntau dua ib zaug, ces qhov kev sib raug zoo uas cov duab sawv cev tsis yog ib qho haujlwm
Yuav ua li cas koj txiav txim siab oxidation lub xeev ntawm carbon nyob rau hauv cov organic tebchaw?
Txhawm rau xam lub xeev oxidation rau carbon, siv cov lus qhia hauv qab no: Hauv C-H daim ntawv cog lus, H raug kho zoo li nws muaj oxidation xeev ntawm +1. Rau cov pa roj carbon monoxide ntau dua electronegative tsis-hlau X, xws li nitrogen, oxygen, sulfur los yog halogens, txhua C-X daim ntawv cog lus yuav ua rau kom lub xeev oxidation ntawm cov pa roj carbon ntau dua 1
Yuav ua li cas koj txiav txim siab npaum li cas ntawm cov kua qaub uas yuav tsum tau neutralize lub hauv paus?
Kev daws qhov teeb meem Acid-Base Neutralization Kauj Ruam 1: Muab xam cov moles ntawm OH-. Molarity = moles / ntim. moles = Molarity x Volume. moles OH- = 0.02 M/100 milliliters. Kauj ruam 2: Xam qhov ntim ntawm HCl xav tau. Molarity = moles / ntim. Volume = moles/molarity. Volume = moles H+/0.075 Molarity
Yuav ua li cas koj txiav txim siab uas yog tus nqi txiav txim kauj ruam?
Tus nqi txiav txim siab kauj ruam yog kauj ruam qeeb tshaj plaws ntawm cov tshuaj tiv thaiv tshuaj uas txiav txim siab qhov nrawm (tus nqi) uas tag nrho cov tshuaj tiv thaiv ua tiav. Teb Tus nqi txiav txim kauj ruam yog kauj ruam thib ob vim nws yog kauj ruam qeeb. 2NO + 2H2 → N2 + 2H2O. Cov intermediates hauv cov tshuaj tiv thaiv no yog N2O2 thiab N2O
