What are the causes of decay?
An unstable nucleus, which can be caused by:excess of neutronsshortage of neutronsmetastable excited state of nucleus
What must happen for an atom to go from an excited state to a ground state so color is seen?
An excited electron spontaneously drops back to its ground state, emitting a photon of light as it does so. <><><><><> The same thing happens in the nucleus. An excited nucleus drops down to a lower energy level, releasing a photon.
What part of the atom orbits the nucleus?
electrons are negatively charged sub atomic particles which surround the nucleus and never leave their orbit unless and until they are excited by a photon(packet of light)
What are ground and excited states?
In an atom, the electron or electrons have a certain normal distance from the atomic nucleus, and when they are at the normal distance, that is described as the ground state. If energy is added to an electron it will move further from the nucleus, or depending upon the amount of energy, may leave the atom entirely. If it moves further from the nucleus it is in an excited state. If it leaves the atom it is ionized.
The state with positively charged atoms energized so that some break free of the nucleus but still move with it is called?
The state with positively charged atoms energized so that some break free of the nucleus is called the excited state. The opposite of an excited state is ground state.
Why an excited atom is electrically neutral?
Even an electron excited to a higher than normal energy level remains sufficiently close to the nucleus of its atom that the atom as a whole remains neutral.
How or where is gamma radiation formed?
In the atomic nucleus as protons and/or neutrons fall from excited states towards their ground state.
What happened to the energyof an electron as it goes farther from the nucleus?
if an electron gains enough energy it jumps to a higher energy level. when this happens the atom is in an "excited" state.
Can hydrogen emit an X-ray?
Yes, a hydrogen nucleus can emit an X-ray if it is excited sufficiently. All excited atomic nuclei can emit electromagnetic radiation. That's how they get coupled to their ground state. It is not unusual for highly energetic X-rays to be radiated from a nucleus that has become energized well above its ground state.
How nucleas of nuclear weapon fission?
A Uranium or Plutonium nucleus fissions (whether in bomb or reactor) by capturing a neutron and entering an unstable excited state. This excited state releases its excess energy a couple nanoseconds later by splitting into two pieces, one about 1/3 and the other about 2/3 the mass of the original nucleus, and 2 or 3 neutrons.
Do all atoms give out radiation?
Any excited atomic nucleus can radiate energy, but we generally only see radioactive atoms emitting radiation.
High-energy light waves that are released from a radioactive nucleus during alpha decay and beta decay?
Gamma rays, which are photons with a certain energy step change, are emitted from the nucleus when the nucleus is returned from an excited state back down to ground state, as often occurs during alpha and beta decay.
