An electron in the first Bohr orbit has a kinetic energy of 13.6 eV. A tiny, positively charged nucleus is around by rotating, negatively charged electrons in set orbits, according to the Bohr Atomic Model.
The Bohr model postulates that the electrons orbit the nucleus at fixed energy levels and also concluded that electron has more energy if it is located away from the nucleus whereas the electrons have less energy if located near the nucleus.
Bohr proposed that electrons do not radiate energy as they orbit nucleus, but exist in state of constant energy that is called stationary states. Bohr's work was based on the emission spectra of hydrogen.
