That would be called a "pulsar".

The neutron star hasn't atoms.
The name "neutron star" some from the fact that the neutron star is mainly composed of neutrons. The gravitational pull of a neutron star is so strong that most matter are crushed into neutrons.

A pulsar.
pulsar
A pulsar is a type of neutron star that emits beams of radiation, including radio waves, from its magnetic poles. As the star rotates, these beams appear to pulse on and off, giving it the appearance of a lighthouse.

The neutron star emitting radio waves and visible light is likely a pulsar. Pulsars are highly magnetized, rotating neutron stars that emit beams of electromagnetic radiation from their magnetic poles. As the pulsar rotates, these beams sweep across our line of sight, causing periodic flashes of light and radio waves to be observed from Earth.
(Quotation from "The Young Oxford Book of Astronomy" Simon and Jacqueline Mitton)"In the intense Magnetic Field of a Neutron star, spiraling electrons generate radio waves that are beamed out like a searchlight. The star spins rapidly, swinging the radio beam across our line of sight, like a lighthouse. Some Pulsars emit light, X-rays and gamma rays as well as Radio waves. The slowest pulsars have pulses about four seconds apart but the most rapid repeat in a matter of milliseconds."Which basically tells you that neutron stars can be pulsars, and the pulsar is not an individual part of a neutron star.
Pulsars. They are very dense neutron stars that rotate quickly and very regularly, emitting radiation pulses towards the earth like a lighthouse.
After going nova some stars turn into neutron star - being composed almost entirely of neutrons. These are very compact and massive and rotate extremely quickly. Typically the magnetic poles of the neutron star do not correspond to the rotational poles so the stars has a rotating magnetic field which is one of the conditions you need to produce radio waves. The radio waves produce by this situation is a beam of radio waves from the star's poles. As this beam sweeps out a cone there are times when it is pointed towards a potential observer and times when it is not. The pulses are the times when the beam flashes over the observer.
If a neutron star's rotational period is fast enough to produce jets (A pulsar), said jets will emit radio waves, with faster periods emitting higher frequency radiation as well as the jets themselves emitting synchrotron radiation. Also, unless the neutron star were 0K, it will emit thermal radiation However, as far as a neutron star that isn't a pulsar, nobody knows if they emit anything but thermal radiation.
Yes, rotating stars can emit directional beams of radio waves. This phenomenon is known as pulsars, which are rapidly rotating neutron stars that emit beams of electromagnetic radiation, including radio waves, along their magnetic axes. The regular pulsing of these beams as they sweep across our line of sight gives the appearance of a pulsating or blinking star.
A neutron star is a small sphere about the size of the earth consisting mainly of neutrons and emitting regular waves of radiation as it rotates which is one of the final stages after the death of a very massive star.
I had to think for this one but me being eleven I'm surprised nobody could answer but there are none on earth that i know of its in space a star, a star gives off radio waves.
