The quantum mechanical model, also known as the electron cloud model, replaced Bohr's model of the atom. This model represents electrons as existing in a diffused cloud of probability in specific energy levels around the nucleus rather than in fixed orbits.
The Bohr model is often referred to as a planetary model of the atom because it depicts electrons orbiting the nucleus in defined paths, similar to how planets orbit the sun. In this model, the nucleus represents the sun, while the electrons are analogous to planets, moving in fixed orbits at specific distances. This visualization helps to simplify the complex behavior of electrons and provides a clear representation of atomic structure. However, this model has limitations and has been refined by more advanced quantum mechanical models.
In Niels Bohr's model of the atom, how are electrons configured?
The model is applied to movement and position of electrons in the atom.
Thompson described his model as plum pudding. Since not many people even know what plum pudding is, i like to describe his model as a scoop of chocolate chip ice cream. Imagine the vanilla ice cream as the positive material and the chips as the negative material.

Electrons in metals can move freely within the material due to the delocalized electron cloud formed by the overlapping atomic orbitals. This allows for high electrical conductivity in metals as the free electrons can carry electric current.

The Thomson model, where electrons are embedded in a positively charged sphere. The Rutherford model, where electrons orbit a central positively charged nucleus. The Bohr model, where electrons move in fixed, circular orbits at specific energy levels. The Quantum mechanical model, where electrons are described by wave functions and exist in electron clouds. The Electron cloud model, which represents the probability of finding an electron in a particular region of space around the nucleus.

Lead can be represented using both the Bohr and Lewis models. In the Bohr model, the electron arrangement is shown in discrete energy levels, while the Lewis model represents the valence electrons as dots around the atomic symbol. Lead has an atomic number of 82, and in the Bohr model, it would typically have four layers of electrons surrounding the nucleus. In the Lewis model, lead would have four valence electrons represented as dots around the element symbol Pb.

The plum pudding model best represents J.J. Thomson's mental image of an atom. In this model, electrons are embedded within a positively charged "pudding," similar to how seeds are embedded in a watermelon.
