2.beta particles
3. gama particles
4.none of these ​

Answer 1

Answer:

Ur required answer is 2 probably..! Have a great day

Answer 2

Answer:

Compare qualitatively the ionizing and penetration power of alpha particles (α) , beta particles (β) , and gamma rays (γ) .

Express the changes in the atomic number and mass number of a radioactive nuclei when an alpha, beta, or gamma particle is emitted.

Write nuclear equations for alpha and beta decay reactions.

Many nuclei are radioactive; that is, they decompose by emitting particles and in doing so, become a different nucleus. In our studies up to this point, atoms of one element were unable to change into different elements. That is because in all other types of changes we have talked about only the electrons were changing. In these changes, the nucleus, which contains the protons which dictate which element an atom is, is changing. All nuclei with 84 or more protons are radioactive and elements with less than 84 protons have both stable and unstable isotopes. All of these elements can go through nuclear changes and turn into different elements.

When the nucleus of a radio nuclide spontaneously gives up its extra energy, that energy is called ionizing radiation. Ionizing radiation may take the form of alpha particles, beta particles, or gamma rays. The process of emitting the radiation is called radioactive decay.
