Ionic kev sib txuas. Raws li peb crude, conceptual txhais, chemical bonds tuaj yeem tsim los ntawm hluav taws xob hloov ntawm atoms los yog los ntawm kev sib koom ntawm electrons . Thaum twg atom poob los yog nce electrons , lawv ua dab tsi hu ua ions. Poob ntawm electrons nplooj ib atom nrog tus nqi zoo net, thiab atom hu ua cation.
Kuj paub, yuav ua li cas thaum atoms nce electrons?
Txawm li cas los xij, yog tias ib yam dab tsi tshwm sim ua ib atom poob los yog nce ib hluav taws xob ces cov atom yuav tsis nyob nruab nrab lawm. Ib atom uas tau txais losses ib hluav taws xob ua ion. Yog nws tau txais ib tug tsis zoo hluav taws xob , nws dhau los ua ib qho tsis zoo ion. Yog nws poob ib hluav taws xob Nws dhau los ua ib qho zoo ion (saib nplooj 10 kom paub ntxiv txog ions).
Qhov thib ob, lub atom puas poob tag nrho nws cov electrons? Keeb Kwm teb: Dab tsi yuav tshwm sim yog ib atom poob tag nrho ntawm nws electrons ? Thaum ib atom poob tag nrho ntawm nws electrons , nws yog hais tias yuav tsum tau ionized kiag li. Cov lus teb yog, thaum tsis muaj electrons nyob ib ncig ntawm lub nucleus, tsis muaj atom yog muaj. Tab sis qhov loj yog kwv yees li 99.8% yog cov nucleus loj (protons + neutrons).
Qhov thib ob, vim li cas lub atom yuav poob ib qho hluav taws xob?
Atoms uas poob electrons tau txais tus nqi zoo raws li qhov tshwm sim vim lawv yog tshuav nrog tsawg tus nqi tsis zoo electrons kom sib npaug cov nqi zoo ntawm cov protons hauv lub nucleus. Kev them nyiaj ions zoo yog npe cations.
Dab tsi yog qhov tsis zoo them atom hu ua?
Negatively them los yog zoo them atom feem ntau hu ua ANION/CATION. Kev piav qhia luv luv: Yog tias ib qho atom poob electrons lossis nce protons, nws yuav muaj qhov zoo nqi thiab yog hu ua ib Cation. Yog ib atom nce electrons los yog poob protons, nws yuav muaj net tus nqi tsis zoo thiab yog hu ua ib Anion.

Thaum twg ib yam khoom nce lossis poob hluav taws xob yuav ua li cas?
Cov hluav taws xob zoo li qub yog tsim cov nqi ntawm cov khoom. Thaum ib yam khoom nce lossis poob hluav taws xob, yuav ua li cas? Thaum ib yam khoom tau txais lossis poob hluav taws xob, nws yuav dhau los ua qhov tsis zoo lossis tsis zoo. Koj muaj ob lub balloons
Yuav ua li cas koj thiaj nrhiav tau lub caij nyoog nce thiab txo?
Cov derivative ntawm ib qho kev ua haujlwm yuav raug siv los txiav txim seb qhov kev ua haujlwm yog nce lossis txo qis ntawm ib ntus hauv nws qhov chaw. Yog tias f '(x) > 0 ntawm txhua qhov taw tes hauv lub caij nyoog I, ces qhov kev ua haujlwm tau hais tias yuav nce ntawm I. f'(x) < 0 ntawm txhua qhov taw tes hauv lub sijhawm kuv, ces qhov ua haujlwm tau hais tias yuav txo qis. ntawm kuv
Qhov loj ntawm protons thiab neutrons thiab electrons piv li cas?
Protons thiab neutrons muaj huab hwm coj zoo sib xws, thaum electrons nyob deb dua, kwv yees li 11800 npaug ntawm qhov loj. Protons raug them zoo, neutrons tsis muaj hluav taws xob, electrons tsis zoo. Qhov luaj li cas ntawm cov nqi yog tib yam, lub cim yog opposite
Puas yog cov viscosities ntawm magmas nce nrog nce feem pua ntawm silica?
Lub viscosities ntawm magmas nce nrog nce feem pua ntawm silica. Kev tawg ntawm Hawaii volcanoes tej zaum yuav piav raws li tawg nyob rau hauv piv rau 1980 Mount St. Helens eruption. Basaltic lavas feem ntau yog kub dua thiab khov dua li andesite lavas
Yuav ua li cas koj xam lub sij hawm nws yuav siv ib yam khoom los poob?
Ntsuas qhov deb ntawm qhov khoom yuav poob hauv ko taw nrog tus pas ntsuas lossis ntsuas daim kab xev. Faib qhov kev ncua deb los ntawm 16. Piv txwv li, yog tias cov khoom yuav poob 128 ko taw, faib 128 los ntawm 16 kom tau 8. Xam cov square root ntawm cov kauj ruam 2 los nrhiav lub sij hawm nws yuav siv cov khoom poob hauv vib nas this
