Chemicals Quote by Dmitri Mendeleev
“Elements which are similar as regards their chemical properties have atomic weights which are either of nearly the same value (eg. Pt, Ir, Os) or which increase regularly (eg. K, Ru, Cs).”
About This Quote
Source Book: Principles of Chemistry, 1869
Elements with similar chemistry share atomic weights that are either close together or follow a regular increase.
In simple terms: Similar elements have close or steadily rising atomic weights.
