From the Bohr Model diagram, assuming the atom is neutral, what element is represented by the diagram?

Bohr Model: In this model negatively charged electrons orbits a positively charged nucleus like the planets orbiting around the sun. Coulomb force between the negatively charged electrons and positively charged nucleus is mathematically akin to the gravitational force of the solar system. Important points are-

The electrons orbit the nucleus in the orbits that have a set energy and size.

Orbital energy is related to its size, highest energy is found in the largest orbit.
The radiation is emitted or absorbed during the movement of electrons from one orbit to the other.

Bohr Model of Hydrogen :

The example of hydrogen atom is simplest in case of Bohr model or for a hydrogen-like ion in which the electrons which is negatively charged orbits around a positively charged nucleus. Only certain electron orbits are allowed and radius of the orbit increases square of n, where n is the principal quantum number. The first line of Balmer series is produced in the 3 to 2 transition. For hydrogen, z=1, this produces a photon of wavelength 656 nanometer.
