What are the characteristics of atomic?
Atoms are the smallest fraction of an element that can exist, and still show the characteristics of the element. Atoms themselves are composed essentially of electrons (1 negative charge), protons (1 positive charge), and neutrons (no charge).
What are the three characteristics of an atom?
Atoms consist of three basic particles: protons, electrons, and neutrons. The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge). The outermost regions of the atom are called electron shells and contain the electrons (negatively charged).
