SUMMARY

This discussion centers on a worksheet related to nuclear reactions and changes, specifically focusing on concepts such as nuclear fission and fusion. Key questions include identifying the type of nuclear reaction that produces energy, the role of the strong nuclear force, and the characteristics of radiation types. Participants emphasize the importance of understanding these concepts rather than simply providing answers, suggesting resources like Wikipedia for further learning.

PREREQUISITES
  • Understanding of nuclear fission and fusion processes
  • Knowledge of radiation types: alpha, beta, and gamma
  • Familiarity with the strong nuclear force and its role in atomic structure
  • Basic concepts of energy changes in chemical and nuclear reactions
NEXT STEPS
  • Research the principles of nuclear fission and fusion
  • Learn about the characteristics and shielding of gamma rays
  • Explore the concept of beta decay and its conditions
  • Study the differences between chemical and nuclear energy changes
USEFUL FOR

Students studying nuclear physics, educators teaching about atomic structure, and anyone seeking to understand the principles of nuclear reactions and energy production.

Helpppp! Pleaseee

Today we had a sub teacher. This worksheet is due tomorrow. Is there any help I can get? Not just answers but explanations?


Confused on a couple questions:

1. The splitting of a nucleus of an atom to obtain energy is called:
fusion
fission
alpha numeric
sunlight

2. Which type of nuclear reaction could produce a virtually limitless and clean source of energy?
fusion
fission
alphanumeric
nuclear detonation

3. Which of the following is a use for nuclear energy?
-Making large explosions
-Injecting radiactive isotopes into humans
-Carbon dating really old things

4.The form of radiation that is a particle consisting of two neutrons and two protons is:
-alpha
-beta
-gamma
-lighta

7. Why is the strong nuclear force needed to keep the nucleus together?
-Protons and electrons repel with each other.
-Protons repel each other
-Protons and electrons attract each other
-Neutrons and protons attract each other

8. The energy involved in a chemical change is ___ than that of a phase change.
-more
-less
-about the same
-none are correct

9. In a ____ change, the molecules and atoms retain their identity but change state.
-phase
-chemical
-nuclear
-positional

10. In a fusion reaction what happens to the missing mass?
- It is converted to steam
- It is converted to ice
- It is converted to energy
- It disappears and is lost for useful purposes

11. The atomic change that produces the largest amount of energy is
- chemical
- physical
- phase
- nuclear

12. When does beta decay occur?
- When an atom has far greater neutrons than protons
- When an atom has far greater protons than neutrons
- When an atom has far greater electrons than protons
- When an atom has far greater protons than electrons
- When an atom has far greater electrons than neutrons

13. Gamma rays can be completely blocked by:
- sheet of paper
- cubed of tin foil
- cubed concrete
- lead pencil

What is a fusion reaction?
11. The atomic change that produces the largest amount of energy is
- chemical
- physical
- phase
- nuclear

I think nuclear is strong. I'm unsure.

12. When does beta decay occur?
- When an atom has far greater neutrons than protons
- When an atom has far greater protons than neutrons
- When an atom has far greater electrons than protons
- When an atom has far greater protons than electrons
- When an atom has far greater electrons than neutrons


13. Gamma rays can be completely blocked by:
- sheet of paper
- cubed of tin foil
- cubed concrete
- lead pencil

I think concrete. The other answers isn't as strong.


*I would like someone to kind of explain a little bit of each to me if possible. My sub handed a worksheet out today, no textbook to refer to nothing. So I'm really stuck.

Also I can define the words to understand more of the question.
 
Do you have a textbook? Wikipedia would be able to help with most, as well. I am sure there are lots of people that could explain each process in detail very well, but aside from it being pretty tedious, the textbook has already done it! :P

Here is one to get you started. http://en.wikipedia.org/wiki/Nuclear_fission
 
surfergirl.. I think you should put some effort in. You should at least be able to narrow down most of the questions to a maximum of 2 answers.

For example: Q1, do you think that sunlight splits an atom?
 
This is pretty funny!
