A stairway is a good model for the energy levels in an atom because there is a 'main floor' ( the nucleus ) and steps ( the energy levels ). The nucleus is the start of the stairway of the energy levels, and the other energy levels go off of the nucleus. The first energy level can hold 2 electrons, the second energy level can hold 8. The third energy level can hold 18, and the fourth energy level can hold 32 electrons. In order for an element to be as stable as a noble gas, the outermost energy level has to be full, so sometimes an atom will gain or lose electrons to fill it's outer energy level. Other times it might share electrons with other atoms, so that they don't have to gain or lose a lot of electrons. An example of this would be H2O ( water ). There is one oxygen atom with two hydrogen atoms connected to it, and sharing their electrons with each other.

An atom of calcium in the Bohr model has four energy levels. These energy levels are designated by the quantum numbers n=1, 2, 3, and 4, corresponding to the first, second, third, and fourth energy levels, respectively.
According to the Bohr model, the single electron of a hydrogen atom moves in circular orbits around the nucleus at specific energy levels. The electron can only occupy certain quantized energy levels and emits energy when transitioning between levels.
De Broglie proposed that electrons in Bohr's model of the atom have wave-like properties, which helps explain the fixed energy levels.
Niels Bohr predicted that the electrons would be found orbiting the nucleus in specific energy levels that could be compared to the rungs of a ladder. He proposed that electrons can only exist in these discrete energy levels and that they move between levels by absorbing or emitting specific amounts of energy. This led to the development of the Bohr model of the atom.
Niels Bohr developed the model of the atom shown in the image. He proposed the planetary model of the atom, where electrons orbit the nucleus in fixed energy levels.
The electrons in the Bohr's model of the atom have been compared to the planets of our solar system. While Sun has been compared to nucleus containing nutrons and protons. Make note that the path of the electrons in a stable atom is circular.
Bohr's model of the atom, proposed by Niels Bohr in 1913, described the atom as having electrons orbiting the nucleus in specific energy levels or shells. It introduced the concept of quantized energy levels and laid the foundation for understanding atomic structure.
The energy levels of an atom hold electrons.
Niels Bohr proposed his model of the atom in 1913, which is known as the Bohr model. This model introduced the idea of quantized energy levels for electrons in an atom, revolutionizing our understanding of atomic structure.
The Bohr model is a simple atomic model that depicts electrons circling the nucleus in specific energy levels or shells. It was proposed by Niels Bohr in 1913 to explain the behavior of electrons in an atom. An example of the Bohr model is the representation of the hydrogen atom, where a single electron orbits the nucleus in discrete energy levels.
