Similarity in chemical properties of the atoms of elements in a group of the Periodic table is most closely related to:

Options

  1. Aatomic numbers
  2. Batomic masses
  3. Cnumber of principal energy levels
  4. Dnumber of valence electrons

Correct answer

A. atomic numbers

Step-by-step solution

If elements are arranged in order of their increasing atomic numbers, element coming at intervals of 2,8,8,18,18,322,8,8,18,18,32 and 32 will have similar physical and chemical properties and thus grouped in one particular group.
