Question

PLEASE HELP ME I BEG YOU I REALLY NEED HELP!!!!

Answer 1

1. they all can be emitted from the nucleus of an atom

2.they have different energies

3.the atom's mass number decreases by 4

4. have an atomic number greater than 83

5. False

6. both b and c

7.reduce the overall environmental impact of the waste by consolidating it

8. 2

9. a fission reaction

Answer 2

Answer:

1. they all can be emitted from the nucleus of an atom

2. they have different energies

3. the atom's mass number decreases by 4

4. False

5. have an atomic number greater than 83

6. both choices b and c

7. reduce the overall environmental impact of the waste by consolidating it

8. 2

Explanation:

1. The particles are all sub-nuclei particles

2. The penetrative power comes from different energies. These are known as ionizing energies. Gamma rays are more ionizing than alpha, followed lastly by beta particles

3. The alpha decay decreases the mass by 4. This is because the alpha particle consists of  protons 2 and  2 neutrons.

4. The energy is given by the relationship: $E = mc^{2}$ where m = mass of particle, c is the speed of light.

5. the mass increase is significant, hence a mass greater than 83

6 both b and c will work

7. this reduces the residual radiation

8. the equation needs to be balanced, hence the missing number is 2
