    Tembelea tovuti hii ili uone meza ya mara kwa mara. Katika meza ya mara kwa mara ya vipengele, vipengele katika safu moja vina idadi sawa ya elektroni ambayo inaweza kushiriki katika mmenyuko wa kemikali. Elektroni hizi zinajulikana kama “elektroni za valence.” Kwa mfano, elementi katika safu ya kwanza zote zina elektroni moja ya valensa—elektroni inayoweza “kuchangia” katika mmenyuko wa kemikali na atomu nyingine. Nini maana ya idadi kubwa inavyoonekana katika mabano?
