| Lub npe | Tooj |
|---|---|
| Atomic Mass | 63.546 atomic mass units |
| Tus naj npawb ntawm Protons | 29 |
| Tus naj npawb ntawm Neutrons | 35 |
| Tus naj npawb ntawm Hluav taws xob | 29 |
Ib yam li ntawd, koj tuaj yeem nug, pes tsawg electrons muaj nyob hauv tooj liab?
29 ib electron
Qhov thib ob, puas yog tooj liab muaj 1 lossis 2 valence electrons? Tooj yog ib qho nthuav heev. Nws yog ib ntawm cov kev hloov pauv uas siv tiag tiag electrons los ntawm ib ntawm lub puab orbitals nyob rau hauv cov tshuaj tiv thaiv. Tooj ( Cu ) muaj ob valence Cu Kuv (cuprous) muaj ib tug valence electron thiab Cu II (kub) muaj ob valence electrons.
Yog li ntawd, koj yuav nrhiav tau tus lej ntawm electrons li cas?
Cov tus naj npawb ntawm electrons nyob rau hauv ib tug nruab nrab atom yog sib npaug rau cov tus lej ntawm protons. Qhov loj tus lej ntawm lub atom (M) yog sib npaug rau cov sum tus lej ntawm protons thiab neutrons nyob rau hauv lub nucleus. Cov tus lej ntawm neutrons yog sib npaug rau qhov sib txawv ntawm qhov loj tus lej ntawm lub atom (M) thiab lub atomic tus lej (Z).
Lub Valency ntawm tooj liab yog dab tsi?
Tooj yog ib qho ntawm cov kev hloov pauv thiab yog li nthuav tawm cov xeev oxidation sib txawv. Nws muaj ob cov khoom muaj nqis : +1 thiab +2 thiab cov atoms raug hu ua Cuperous (+1 valency ) thiab Cupric (+2 valency ). Tooj muaj tus lej atomic ntawm 29 thiab nws cov kev teeb tsa hluav taws xob yog 1s2, 2s2, 2p6, 3s2, 3p6, 3d10, 4s1.

Muaj pes tsawg lub xov tooj cua tsis muaj hluav taws xob nyob hauv smartphones?
Ntawm 83 qhov ruaj khov thiab tsis muaj hluav taws xob nyob hauv lub rooj zaum, tsawg kawg 70 tuaj yeem pom hauv smartphones. Raws li qhov muaj txiaj ntsig zoo tshaj plaws, tag nrho ntawm 62 hom hlau sib txawv mus rau hauv nruab nrab lub xov tooj ntawm tes, nrog rau qhov uas hu ua cov hlau tsis tshua muaj ntiaj teb ua lub luag haujlwm tseem ceeb
Yuav ua li cas muaj pes tsawg tus tooj liab atoms koj yuav tsum tau kab ntawm ib sab los tsim ib kab 1'm ntev?
Los ntawm kev sib piv, lub ntiaj teb cov pej xeem tsuas yog hais txog 7? 109 neeg. Yog tias koj tuaj yeem ua kab 100,000,000 tooj liab atoms ib sab, lawv yuav tsim ib txoj kab ntev li 1 cm
Koj puas paub tias muaj pes tsawg lub orbitals nyob hauv lub plhaub?
Tus naj npawb ntawm orbitals nyob rau hauv ib lub plhaub yog cov square ntawm tus thawj quantum tooj: 12 = 1,22 = 4, 32 = 9. Muaj ib tug orbitalin ib tug subshell (l = 0), peb orbitals nyob rau hauv ap subshell (l = 1) , thiab tsib orbitals hauv ad subshell (l = 2). Yog li ntawd, tus naj npawb ntawm orbitals hauv subshell yog 2(l) +1
Muaj pes tsawg protons nyob rau hauv tooj liab?
29 Kuj paub, pes tsawg protons electrons thiab neutrons nyob rau hauv tooj liab? Tooj liab muaj tus lej atomic ntawm 29 , yog li nws muaj 29 proton thiab 29 ib electron . Qhov hnyav atomic (tej zaum hu ua atomic mass) ntawm ib lub atom yog kwv yees los ntawm cov lej ntawm cov protons thiab cov naj npawb ntawm cov neutrons hauv lub nucleus ntawm lub atom.
