Essential Chemistry for IGCSE - Metals And Reactivity (Section 4 - No. 49)
Which of the following factors influence the reactivity of metals?
The size of the metal atoms.
The number of valence electrons.
The number of electron shells.
The atomic mass of the metal.
Explanation
The reactivity depends heavily on the ease with which the metal atoms lose electrons, influenced by the number of valence electrons and the distance of those electrons from the nucleus (number of shells).
