Maendeleo ya meza ya mara kwa mara katikati ya miaka ya 1800 ilitoka kwa uchunguzi kwamba kulikuwa na uhusiano wa mara kwa mara kati ya mali ya vipengele. Wanakemia, ambao wana ufahamu wa tofauti za mali hizi, wameweza kutumia ujuzi huu kutatua changamoto mbalimbali za kiufundi. Kwa mfano, silicon na semiconductors nyingine huunda uti wa mgongo wa umeme wa kisasa kwa sababu ya uwezo wetu wa kutengeneza vizuri mali za umeme za vifaa hivi. Sura hii inahusu mali muhimu ya metali mwakilishi, metalloids, na nonmetali katika meza ya mara kwa mara.
