JEE Mains · Chemistry · STD 11 - 3. Classification of elements and periodicity in properties
Similarity in chemical properties of the atoms of elements in a group of the Periodic table is most closely related to
- A atomic numbers
- B atomic masses
- C number of principal energy levels
- D number of valence electrons
Answer & Solution
Correct Answer
(A) atomic numbers
Step-by-step Solution
Detailed explanation
If elements are arranged in order of their increasing atomic numbers, element coming at intervals of \(2, 8, 8, 1 8, 1 8, 32\) and \(32\) will have similar physical and chemical properties and thus grouped in one particular group.
