Why are Niels Bohr orbits called stationary state?
Niels Bohr called the orbits "stationary states" because in these states, electrons do not emit electromagnetic radiation or lose energy, resulting in stable orbits. These stationary states are characterized by specific energy levels, and transitions between these states result in quantized energy exchanges. This concept helped explain the stability of the atom and laid the foundation for quantum mechanics.
Why do elements on their gaseous state absorb and emit radiation?
Elements in their gaseous state absorb and emit radiation due to the behavior of their electrons. When energy is supplied to a gas, electrons can become excited and jump to higher energy levels. When these electrons return to their original levels, they release energy in the form of radiation, which is often seen as light. The specific wavelengths of this radiation depend on the unique energy levels of the electrons in the atoms of the element, leading to characteristic emission and absorption spectra.
Why a static charge does not emit radiation?
A static charge does not emit radiation because it does not involve the accelerating or decelerating motion of charged particles, which is necessary to produce electromagnetic radiation. In a static charge situation, the charges are stationary or in constant motion, so there is no changing electric or magnetic field to generate radiation.
What kind of radiation does a black hole emit?
Black holes are believed to emit something called Hawking radiation.
Do atoms in excited states emit radiation randomly at any wavelength?
No, atoms in excited states emit radiation at specific wavelengths, corresponding to the energy difference between the excited state and the ground state. This emission occurs randomly when the atom returns to a lower energy state by releasing a photon.
Do electrons emit radiation only when in stationary states?
no, only when accelerated
Exactly what do vibrating electrons emit?
Classical they will emit electromagnetic waves (light and radio waves). Quantum effects might limit this since if the electrons are in the ground state (or all lower states are occupied) they can not emit any photons (quanta of electromagnetic waves).

How did Bohr's model of the hydrogen atom differ from the previous model?
Bohr stated that electrons do not emit radiation unless they change energy states. Bohr stated that the energy of electrons exist in discrete states.
Which type of radiation does strontium-90 emit?
Strontium-90 emits beta radiation when it decays. Beta radiation consists of fast-moving electrons.
Why a static charge does not emit radiation?
A static charge does not emit radiation because it does not involve the accelerating or decelerating motion of charged particles, which is necessary to produce electromagnetic radiation. In a static charge situation, the charges are stationary or in constant motion, so there is no changing electric or magnetic field to generate radiation.
What type of radiation does P-32 emit?
The radioactive decay of Phosphorus-32 emits only betaparticles (i.e. electrons) with a halflife of slightly longer than two weeks. No electromagnetic radiation at all is emitted.
Is an electron radiation?
Yes, electrons can emit radiation when they are accelerated or decelerated. This radiation is called bremsstrahlung, which occurs when electrons interact with matter and release energy in the form of X-rays.
Do light bulbs emit radiation, and if so, what type of radiation do they emit?
Yes, light bulbs emit radiation in the form of visible light.
At what temperature does Lithium-6 emit radiation?
Any material will emit blackbody radiation at any temperature. Lithium 6 will never emit ionizing radiation.
Why elements in gaseous state emit radiation?
They do not! Most gases do not emit radiation.
Do all light waves emit radiation?
Light waves do not emit radiation, light waves are radiation.
