What happens to an atom if the electrons in the outer shell are altered?

Question

Quizplus · Accepted Answer

The properties of an atom are determined by the number and arrangement of its electrons, particularly those in the outermost shell or valence shell. Altering the number or arrangement of these electrons can change the chemical properties of the atom, such as its reactivity or bonding behavior, without necessarily changing its identity as a specific element. Therefore, choice C is the best answer. Choices A and B are incorrect because changing the arrangement of electrons does not necessarily involve changes to the atom's nucleus or cause it to break apart. Choice D is also incorrect because changing the number or arrangement of electrons can alter the atom's properties, but it does not change the fundamental nature of the element itself.
