What happens to the energy of the electrons in the orbits of each orbit increases
The electrons can only travel in certain orbits: at a certain discrete set of distances from the nucleus with specific energies. # The electrons of an atom revolve around the nucleus in orbits. These orbits are associated with definite energies and are also called energy shells or energy levels
Bohr did not speak of fixed LOCATIONS of electrons, he spoke of fixed energy levels. His name for such energy levels was "orbits" or "orbitals."

Electrons i.e. negatively charged particles.
Energy must be emitted for an electron to return to the ground state. This energy typically occurs in the form of a photon--a particle/wavelet of light. Flourescent bulbs, for example, conduct a current through a gas knocking electrons into higher, more exicted orbits. As the electrons decay into lower orbits, light is emitted, producing the flourescent glow.
orbits are like energy levels where probability of finding electron is maximum
The Bohr model addressed the problem of decaying orbits of the electrons, which was a problem with the Rutherford planetary model. If electrons are located in discrete energy levels, their orbits do not decay, and the atom does not collapse in on itself.
According to the Bohr model, electrons move in atoms by circling the nucleus. The closer the electron orbits the nucleus, the lower energy state, or energy level it has. The further it orbits from the nucleus, the higher energy state it has.
The atomic number of calcium is 20 as it has 20 protons and 20 electrons, they are located outside the Nucleus in the orbits known as energy levels, and are commonly known as shells of the atom. in the first energy level there are 2 electrons, in the second energy level there are 8 electron, in the third energy level there are 8 electrons, and in the fourth energy level there are 2 electrons.
