Question

Use the drop-down menus to identify the definition of radiation and the different types of radioactive emissions.

______is the process of emitting radiant energy in the form of waves or particles.
______is two protons and two neutrons bound together into a particle identical to a helium nucleus. is a negatively charged electron emitted by the nucleus.
______is the radioactive decay of an atom that releases a photon, which results from a redistribution of electric charge within a nucleus.

Alpha particle

Beta particle

Gamma ray

Radiation

Help me quickly please! I don't get it! T.T

Answer 1

Step-by-step 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
`^(4)_(2)\alpha`.

A beta particle is a particle with a negatively charged electron. Symbol of a beta particle is
`^(0)_(-1)\beta`.

A gamma particle is basically a photon of electromagnetic radiation with a short wavelength.

Symbol of a gamma particle is
`^(0)_(0)\gamma`.

Therefore, we can conclude that the definition of radiation and the different types of radioactive emissions are as follows.

• 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.

Answer 2

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 ;)
