What is a key characteristics of a atom

OpenStudy (dannyrod2000):

All matter consists of particles called atoms. This is a list of the basic characteristics of atoms: Atoms cannot be divided using chemicals. They do consist of parts, which include protons, neutrons, and electrons, but an atom is a basic chemical building block of matter. Each electron has a negative electrical charge. Each proton has a positive electrical charge. The charge of a proton and an electron are equal in magnitude, yet opposite in sign. Electrons and protons are electrically attracted to each other. Each neutron is electrically neutral. In other words, neutrons do not have a charge and are not electrically attracted to either electrons or protons.
