Explanation:

To solve this, we recall John Dalton's atomic theory. Elements are composed of atoms, and all atoms of a given element are identical. So the first blank should be "Elements" (as elements are groups), the second blank "atoms" (what the group is made of), and the third blank "identical" (property of atoms in an element).
