검증된 단계별 안내1
Understand that reactivity in metals generally refers to how readily a metal loses electrons to form positive ions (cations) during chemical reactions.
Recall that the periodic table groups metals into families based on similar properties, including reactivity.
Recognize that alkali metals (Group 1) have a single electron in their outermost shell, which they tend to lose very easily, making them highly reactive.
Compare alkali metals to alkaline earth metals (Group 2), transition metals, and noble metals, noting that noble metals are known for their low reactivity and resistance to corrosion.
Conclude that because alkali metals lose their outer electron most readily, they are considered the most reactive family of metals on the periodic table.
