검증된 단계별 안내1
Understand the question is asking for the smallest particle of an element that retains the element's identity.
Recall that an atom is the fundamental unit of an element, meaning it cannot be broken down further without losing the properties of that element.
Recognize that a molecule is made up of two or more atoms bonded together, so it is not the smallest particle of an element.
Know that an ion is an atom or molecule that has gained or lost electrons, changing its charge but not necessarily its elemental identity.
Remember that an electron is a subatomic particle and does not represent the element itself, but rather a component of an atom.
