WebBohr’s model was a valuable tool in predicting some atomic behavior, but the atomic theory still had room for improvement. According to the current theory, there are regions inside the atom where electrons are likely to be found —these regions are called electron clouds. Electron clouds are related to the paths described in Bohr’s model. WebThe Atomic Orbital Model is the currently accepted model of the electrons in an atom.It is also sometimes called the Wave Mechanics Model.In the atomic orbital model, the atom consists of a nucleus surrounded by orbiting electrons.
