According to Lother Meyer, highly electropositive alkali metals occupy the peaks of the atomic volum — Periodic Table and Periodicity Chemistry Question

💡 Solution & Explanation

In the Lother Meyer curve (Atomic Volume vs Atomic Mass), the major peaks are occupied by the alkali metals. From Lithium to Cesium, these are $Li, Na, K, Rb,$ and $Cs$, which equates to exactly 5 distinct peaks shown in historical plots.
