Practical Atomic Model offers practical explanations for atoms and their behaviors.All of the evidence supports an atom's electrons are in a defined sequence of circular (constant radius) orbits from the nucleus. Chemists have used these electron configurations for decades. In 1916, Gilbert Lewis defined a dot structure for a simple method of managing each element's circular ring of valence electrons. Its use continues after 100 years, though with known limitations. For the multiple lobed orbitals to persist in an atomic model, they require evidence for its crucial claim that an electron's location is uncertain in the pdf shells and can be found only by defining probabilities or from a wave function.Better, practical explanations in an atomic model are offered here, such as: a) building a stable nucleus using protons and electrons, as affected by the odd or even nucleon counts, b) explaining how their mutual forces provide the strong and weak interaction forces in a nucleus; c) describing the actions of radioactive decay, which include interactions between the nucleus and the inner ring of electrons; d) the origin of atomic mass defect;e) suggesting new names for the rings of electrons to suit their order and capacity in the configuration; and f) describing an atom's interactions with light.
