Iron, an element with the chemical symbol Fe, is an important element. It is used to make steel and is part of the substance that transports oxygen throughout the human body. Which statement about Fe is supported by the modern atomic theory but not John Dalton’s theory?

The element iron is composed of small particles called atoms.

The electrons of iron have probable locations in a region of space around the nucleus.

Iron atoms combine with other atoms in whole number ratios to form compounds.

Chemical reactions that involve iron do not create new atoms of iron.

The statement about Fe that supports the modern atomic theory but not John Dalton's theory would be that the electrons of iron have probable locations in a region of space around the nucleus.

This is because John Dalton's atomic theory does not recognize the existence of protons, neutrons, and electrons in atoms.

Recall John Dalton's atomic theory:

all elements consist of indivisible particles called atoms.
atoms of the same elements are identical and different from atoms of other elements
atoms cannot be created and neither can they be destroyed
atoms of different elements can combine in a simple whole-number ratio to form compounds

Thus, the postulate of the modern atomic theory that says that atoms have a structure with protons and neutrons in its nucleus and electrons in its outer shells negates one of the theories of Dalton.
