Essential Chemistry for IGCSE - Metals And Reactivity (Section 4 - No. 7)
Which factors affect the reactivity of metals?
The number of protons.
The number of electron shells.
The attraction between the nucleus and outer shell electrons.
The atomic mass.
Explanation
Reactivity depends on how easily the metal loses electrons, which is influenced by the nuclear charge, the number of electron shells, and the shielding effect of inner electrons.
