Tenaga pengionan bertambah dari kiri ke kanan satu kala dan menurun dari atas ke bawah satu kumpulan. </p>    </div><noscript><img src="https://login.wikimedia.org/wiki/Special:CentralAutoLogin/start?type=1x1" alt="" width="1" height="1" style="border: none; position: absolute;"></noscript> <div class="printfooter" data-nosnippet="">Diambil daripada "<a dir="ltr" href="https://ms.wikipedia.org/w/index.php?title=Tenaga_pengionan&oldid=3187193">https://ms.wikipedia.org/w/index.php?title=Tenaga_pengionan&oldid=3187193</a>"</div></div> <div id="catlinks" class="catlinks" data-mw="interface"><div id="mw-normal-catlinks" class="mw-normal-catlinks"><a href="/wiki/Khas:Kategori" title="Khas:Kategori">Kategori</a>: <ul><li><a href="/wiki/Kategori:Ion" title="Kategori:Ion">Ion</a></li><li><a href="/wiki/Kategori:Fizik_molekul" title="Kategori:Fizik molekul">Fizik molekul</a></li><li><a href="/wiki/Kategori:Fizik_atom" title="Kategori:Fizik atom">Fizik atom</a></li><li><a href="/w/index.php?title=Kategori:Ciri-ciri_kimia&action=edit&redlink=1" class="new" title="Kategori:Ciri-ciri kimia (laman tidak wujud)">Ciri-ciri kimia</a></li><li><a href="/wiki/Kategori:Kimia_kuantum" title="Kategori:Kimia kuantum">Kimia kuantum</a></li></ul></div><div id="mw-hidden-catlinks" class="mw-hidden-catlinks mw-hidden-cats-hidden">Kategori tersembunyi: <ul><li><a href="/wiki/Kategori:Rencana_dengan_templat_hatnote_yang_menyasarkan_halaman_yang_tidak_wujud" title="Kategori:Rencana dengan templat hatnote yang menyasarkan halaman yang tidak wujud">Rencana dengan templat hatnote yang menyasarkan halaman yang tidak wujud</a></li></ul></div></div> </div> </main> </div> <div class="mw-footer-container"> <footer id="footer" class="mw-footer" > <ul id="footer-info"> <li id="footer-info-lastmod"> Laman ini kali terakhir disunting pada 00:04, 3 Mei 2013.</li> <li id="footer-info-copyright">Teks disediakan di bawah <a rel="nofollow" class="external text" href="https://creativecommons.org/licenses/by-sa/4.0/deed.ms">Lesen Creative Commons Pengiktirafan/Perkongsian Serupa</a>; terma tambahan mungkin digunapakai.
