which statement best describes a major difference between different types of elements. a only some elements…

Brief Explanations:

The identity of an element is determined by the number of protons in its nucleus. Atoms of different elements have different numbers of protons (and usually different numbers of electrons to maintain electrical neutrality). This is a fundamental concept in chemistry. Options A and B are incorrect as all elements have atoms with sub - atomic particles and all elements are composed of atoms with electrons. Option C is incorrect as the location of the nucleus is not a defining characteristic to differentiate elements.

Answer:

D. The atoms of different elements have different numbers of protons and electrons.
