radiation :
-> is the process of emitting radiant energy in the form of waves or particles.
alpha particle :
-> is two protons and two neutrons bound together into a particle identical to a helium nucleus.
beta particle :
-> is a negatively charged electron emitted by the nucleus.
gamma ray :
-> is the radioactive decay of an atom that releases a photon, which results from a redistribution of electric charge within a nucleus.
I just took it, these are the correct answers ;)
Explanation:
Radiation is defined as an electromagnetic energy which travels in space in the form of waves or particles.
An alpha particles is basically a helium nucleus and it contains 2 protons and 2 neutrons.
Symbol of an alpha particle is [tex]^{4}_{2}\alpha[/tex].
A beta particle is a particle with a negatively charged electron. Symbol of a beta particle is [tex]^{0}_{-1}\beta[/tex].
A gamma particle is basically a photon of electromagnetic radiation with a short wavelength.
Symbol of a gamma particle is [tex]^{0}_{0}\gamma[/tex].
Therefore, we can conclude that the definition of radiation and the different types of radioactive emissions are as follows.
