title="Fisika">fisika</a> is 'n <b>valenselektron</b> 'n <a href="/wiki/Elektron" title="Elektron">elektron</a> in die buitenste <a href="/wiki/Elektronskil" title="Elektronskil">elektronskil</a> wat met 'n atoom geassosieer word, en wat kan deelneem aan die vorming van 'n <a href="/wiki/Chemiese_binding" title="Chemiese binding">chemiese binding</a> as die buitenste skil nie toe is nie; in 'n enkele <a href="/wiki/Kovalente_binding" title="Kovalente binding">kovalente binding</a> dra albei atome in die binding een valenselektron by om 'n gedeelde paar te vorm. </p><p>Die aanwesigheid van valenselektrone kan die chemiese eienskappe van die element bepaal, soos die <a href="/wiki/Valensie" title="Valensie">valensie</a> daarvan - of dit met ander <a href="/wiki/Element" class="mw-redirect" title="Element">elemente</a> kan bind en, indien wel, hoe geredelik en met hoeveel. Op hierdie manier is die reaktiwiteit van 'n gegewe element baie afhanklik van die elektroniese konfigurasie daarvan. Vir 'n hoofgroepelement kan 'n valenselektron slegs in die buitenste elektronskil bestaan; vir 'n <a href="/wiki/Oorgangsmetaal" title="Oorgangsmetaal">oorgangsmetaal</a> kan 'n valenselektron ook in 'n binneste skil wees. </p><p>'n Atoom met 'n geslote skil van valenselektrone (wat ooreenstem met 'n <a href="/wiki/Elektronkonfigurasie" title="Elektronkonfigurasie">elektronkonfigurasie</a> s<sup>2</sup> p<sup>6</sup> vir hoofgroepelemente of d<sup>10</sup> s<sup>2</sup> p<sup>6</sup> vir oorgangsmetale) is geneig om chemies onreaktief te wees. Atome met een of twee valenselektrone meer as 'n geslote skil is baie reaktief as gevolg van die relatiewe lae energie om die ekstra valenselektrone te verwyder om 'n positiewe <a href="/wiki/Ioon" title="Ioon">ioon</a> te vorm. 'n Atoom met een of twee elektrone minder as 'n gevulde skil het is reaktief vanweë die neiging om die ontbrekende valenselektrone te verkry en 'n negatiewe ioon te vorm, of om valenselektrone te deel en 'n kovalente binding te vorm. </p><p>Soortgelyk aan 'n kernelektron, het 'n valenselektron die vermoë om energie op te neem of vry te stel in die vorm van 'n <a href="/wiki/Foton" title="Foton">foton</a>. 'n Energietoename kan veroorsaak dat die elektron na 'n buitenste skil beweeg (op spring); dit staan bekend as atoom-opwekking. Of die elektron kan selfs loskom van die skil van die atoom; dit is ionisasie om 'n positiewe ioon te vorm. Wanneer 'n elektron energie verloor (wat veroorsaak dat 'n foton uitgestraal word), kan dit beweeg na 'n binneste skil wat nie heeltemal vol is nie. </p> <meta property="mw:PageProp/toc" /> <div class="mw-heading mw-heading2"><h2 id="Oorsig">Oorsig</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Valenselektron&veaction=edit&section=1" title="Wysig afdeling: Oorsig" class="mw-editsection-visualeditor"><span>wysig</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Valenselektron&action=edit&section=1" title="Edit section's source code: Oorsig"><span>wysig bron</span></a><span class="mw-editsection-bracket">]</span></span></div> <div class="mw-heading mw-heading3"><h3 id="Elektronkonfigurasie">Elektronkonfigurasie</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Valenselektron&veaction=edit&section=2" title="Wysig afdeling: Elektronkonfigurasie" class="mw-editsection-visualeditor"><span>wysig</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Valenselektron&action=edit&section=2" title="Edit section's source code: Elektronkonfigurasie"><span>wysig bron</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Die elektrone wat valensie bepaal en hoe 'n atoom chemies reageer is dié met die hoogste energie. </p><p>Vir 'n hoofgroepelement word die valenselektrone gedefinieer as die elektrone wat in die elektronskil met die hoogste hoofkwantumgetal <i>n</i> vorkom.<sup id="cite_ref-Petrucci_1-0" class="reference"><a href="#cite_note-Petrucci-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> Die aantal valenselektrone wat dit mag hê, hang dus op 'n eenvoudige manier af van die elektronkonfigurasie. Die elektroniese konfigurasie van <a href="/wiki/Fosfor" title="Fosfor">fosfor</a> (P) is byvoorbeeld 1s<sup>2</sup> 2s<sup>2</sup> 2p<sup>6</sup> 3s<sup>2</sup> 3p<sup>3</sup> sodat daar 5 valenselektrone (3s<sup>2</sup> 3p<sup>3</sup>) is, wat ooreenstem met 'n maksimum valensie vir P van 5 (soos in die molekule PF<sub>5</sub>); hierdie konfigurasie word normaalweg afgekort tot [Ne]3s<sup>2</sup> 3p<sup>3</sup>, waar [Ne] die kernelektrone aandui waarvan die konfigurasie identies is aan die van die <a href="/wiki/Edelgas" class="mw-redirect" title="Edelgas">edelgas</a> <a href="/wiki/Neon" title="Neon">neon</a>. </p><p>Oorgangselemente het egter gedeeltelik gevulde d-energievlakke, wat baie naby aan energie is aan die s-vlak.<sup id="cite_ref-chemguide2010_2-0" class="reference"><a href="#cite_note-chemguide2010-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup> Dus, in teenstelling met hoofgroepelemente, word 'n valenselektron vir 'n oorgangsmetaal gedefinieer as 'n elektron wat buite 'n edelgaskern woon.<sup id="cite_ref-Miessler2008_3-0" class="reference"><a href="#cite_note-Miessler2008-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup> Die d-elektrone in oorgangsmetale gedra hulle gewoonlik as valenselektrone, alhoewel hulle nie in die buitenste skil is nie.

In hierdie atoom het 'n 3d-elektrone energie soortgelyk aan die van 'n 4s-elektrone, en baie hoër as die van 'n 3s- of 3p-elektrone. In werklikheid is daar moontlik sewe valenselektrone (4s<sup>2</sup> 3d<sup>5</sup>) buite die argonagtige kern; dit stem ooreen met die chemiese feit dat mangaan 'n oksidasietoestand van so hoog as +7 kan hê (in die <a href="/wiki/Permanganaat" title="Permanganaat">permanganaatioon</a>: [MnO]<sup> 4-</sup>). </p><p>Hoe verder regs in elke oorgangsmetaalreeks, hoe laer is die energie van 'n elektron in 'n d-skil en hoe minder het so 'n elektron valensie-eienskappe.
