Mendeleev's periodic law states that properties of elements are a periodic function of their:
AMelting points
BAtomic numbers
CValence electrons
DAtomic masses
Answer & Solution
Correct answer: D. Atomic masses
1. Mendeleev found that elements with similar properties recur at definite intervals.
2. He stated: properties of elements are a periodic function of their atomic masses.
3. This is distinct from the modern law, which uses atomic numbers.
4. Rule out B: atomic numbers belong to the modern periodic law of Moseley.
