po periodama. Periodne sisteme, gotovo identične, nezavisno jedan od drugog razvili su 1869. godine ruski hemičar <a href="/wiki/Dmitrij_Ivanovi%C4%8D_Mendeljejev" class="mw-redirect" title="Dmitrij Ivanovič Mendeljejev">Dmitrij Ivanovič Mendeljejev</a> (1834-1907), a samo nekoliko mjeseci kasnije i njemački hemičar <a href="/wiki/Lothar_Meyer" title="Lothar Meyer">Lothar Meyer</a> (1830–1895). Periodni sistem ima i historijsku vrijednost za predviđanje otkrića novih elemenata i njihovih osobina.

To su elementi sa rednim brojem 1 (<a href="/wiki/Vodik" title="Vodik">vodik</a>) i 2 (<a href="/wiki/Helij" title="Helij">helij</a>). Oni u pregledu periodnog sistema zauzimaju gornji, prvi red (koji se naziva i <a href="/w/index.php?title=Elementi_1._periode&action=edit&redlink=1" class="new" title="Elementi 1. periode (stranica ne postoji)">1. perioda</a>). </p><p>Atomi elementa koji slijedi nakon prva dva (<a href="/wiki/Litij" title="Litij">litij</a>, redni broj 3), imaju po tri protona i tri elektrona. Međutim, treći elektron nalazi se usamljen u elektronskoj ljusci iznad <i>k-ljuske</i>, koja se naziva <i>l-ljuska</i>. Ta druga ljuska ima prostora za najviše osam elektrona. Nakon litija, postoji sedam drugih elemenata (sa ukupno četiri do deset protona i isto toliko elektrona) koji zajedno sa litijem sačinjavaju drugi red periodnog sistema odnosno <a href="/w/index.php?title=Elementi_2._periode&action=edit&redlink=1" class="new" title="Elementi 2. periode (stranica ne postoji)">2. periodu</a>. Atomi elementa sa rednim brojem 11 (<a href="/wiki/Natrij" title="Natrij">natrij</a>) imaju po još jednu dodatnu ljusku, koja je iznad <i>l-ljuske</i> a u kojoj kruži jedan elektron. U toj trećoj elektronskoj ljusci, zvanoj <i>m-ljuska</i>, opet ima "mjesta" za ukupno osam elektrona.<sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-bracket">[</span>a<span class="cite-bracket">]</span></a></sup> U skladu s tim, nakon natrija postoji još sedam elemenata sve do rednog broja 18 (<a href="/wiki/Argon" title="Argon">argon</a>) u trećem "redu" periodnog sistema. To su <a href="/w/index.php?title=Elementi_3._periode&action=edit&redlink=1" class="new" title="Elementi 3. periode (stranica ne postoji)">elementi 3. periode</a>. </p><p>Elektroni koji se nalaze u ljusci najudaljenijoj od atomske jezgre nazivaju se vanjski ili valentni elektroni. Oni igraju važnu ulogu u građenju mnogih <a href="/wiki/Hemijski_spoj" title="Hemijski spoj">hemijskih spojeva</a> iz atoma različitih ili istih elemenata. Broj valentnih elektrona kod elemenata u nekom "redu" (periode) uvijek raste s lijeva na desno kod prve tri periode. Kod atoma vodika i helija postoji jedan odnosno oba elektrona u elektronskoj ljusci su ujedno i vanjski (valentni). Kod atoma elemenata iz druge i treće periode, vanjski elektroni se nalaze u <i>l-</i> odnosno <i>m-ljusci</i>, tako da naprimjer litij i natrij imaju po jedan, dok <a href="/wiki/Neon" title="Neon">neon</a> i <a href="/wiki/Argon" title="Argon">argon</a> po osam vanjskih elektrona. </p><p>Ako se uporede osobine elemenata čiji atomi imaju isti broj valentnih elektrona, može se primijetiti veliki broj sličnosti i podudarnosti. Ove sličnosti naročito dolaze do izražaja kroz poredak elemenata u periodnom sistemu. Elementi koji imaju samo jedan od mogućih osam valentnih elektrona u svojoj vanjskoj ljusci nalaze se na prvim mjestima svoje periode. Na osnovu tako poredanih elemenata proizilazi prva kolona u periodnom sistemu koja se naziva <i>prva glavna grupa</i>, a koja obuhvata elemente poznate pod pojmom <a href="/wiki/Alkalni_metali" title="Alkalni metali">alkalni metali</a>. Elementi koji u svojoj vanjskoj ljusci imaju po sedam valentnih elektrona nalaze se na pretposljednjem mjestu u svojoj periodi.

Elementi koji u vanjskoj ljusci imaju po osam elektrona, odnosno koji imaju u potpunosti popunjenu vanjsku ljusku, nalaze se na posljednjem mjestu u svojoj periodu, u takozvanoj <i>osmoj glavnoj grupi</i> te se nazivaju <a href="/wiki/Plemeniti_plinovi" title="Plemeniti plinovi">plemeniti plinovi</a>.
