... Reactivity of metals is based on the ease with which they lose valence electrons to achieve a stable octet, or noble gas configuration. Group 1A elements, [noble gas]ns1, lose their one valence electron, forming an ion with a 1+ charge. Group 2A elements, [noble gas]ns2, lose their two valence elect ...
