Essential Chemistry for IGCSE - Metals And Reactivity (Section 5 - No. 25)
Which of the following are true concerning the relative reactivity of metals?
Metals with fewer electron shells are generally more reactive.
Metals that readily lose electrons are more reactive.
Metals with a higher number of outer electrons are more reactive.
Metals with a smaller nuclear charge tend to be more reactive.
Explanation
Reactivity is related to how easily the metal loses electrons. Fewer electron shells and high attraction to the nucleus lead to greater reactivity.
