Particles or electromagnetic waves
alpha particles
Charged particles will be deflected by an electric field. The movement of any charged particle through an electric field will cause that charged particle to be attracted by one pole of the field and repelled by the other. That leaves uncharged particulate radiation, like a neutron, and electromagnetic radiation that will not be deflected by an electric field. The electromagnetic radiation will include X-rays and gamma rays.
During radioactive decays heat is released.
Can be alpha, beta particles in radioactive decay, or neutrons in fission. There is also gamma ray energy which is part of the EM spectrum I believe the answer your looking for is Radiation
Depending on the specific element and isotope it can release neutrons, alpha particles (Helium-4 nuclei), beta particles (electrons and positrons), and gamma radiation (energy in the form of electromagnetic radiation)
Particles or electromagnetic waves
Whenever the electron falls from an excited state to a lower level, energy is released in the form of electromagnetic radiation. The Electromagnetic radiation can be light of different wavelengths and therefore different colors
alpha particles
Ultraviolet is a part of electromagnetic spectrum. It is a radiation released from the sun.
There is not one, but many radioactive elements. Radioactive isotopes, to be more precise - because sometimes, one isotope may be stable, while another isotope of the same element is radioactive. All, or most, elements have radioactive isotopes.
The Sun releases energy in the form of heat and electromagnetic radiation.
Gamma radiation isn't a form of decay as it doesn't create a new atom but gamma radiation is an electromagnetic wave.
Your question is very hard to understand, but the process that releases electromagnetic radiation in the sun is called fusion.
Yes but it can't stop all radiation going in the atmosphere, it slow slows it down.
radon-222
The energy released in a radioactive decay arises because the nucleus is moving from one energy level to a lower energy one. The link below gives a good outline explanation in the Explanation section.
