Smallest piece of matter that still retains the property of the element

Smallest piece of matter that still retains the property of the element

• A. Protons
• B. Electrons
• C. Neutrons
• D. Atom

Answer: (D)

Elements have their own unique chemical behavior because of the way their atoms are built and arranged. The smallest piece that still shows that element’s properties is the atom. An atom includes a nucleus of protons and neutrons and electrons circling around it; the element’s identity and how it reacts come from the number of protons (which defines the element) and the electron arrangement that governs bonding. If you break an atom into subatomic parts, those parts by themselves don’t exhibit the element’s characteristic chemical properties. A single proton, electron, or neutron doesn’t behave like the element—so the atom, not smaller pieces, is the smallest unit that retains the element’s properties.
