Discussion Overview

The discussion revolves around a worksheet on nuclear reactions and changes, with participants seeking help on specific questions related to nuclear energy, types of nuclear reactions, and properties of radiation. The scope includes conceptual understanding and application of nuclear physics principles.

Discussion Character

  • Homework-related
  • Exploratory
  • Technical explanation

Main Points Raised

  • One participant expresses confusion about various questions on the worksheet and requests explanations rather than just answers.
  • Another participant asks for the original poster's thoughts on the questions to provide better assistance.
  • Several questions are listed, including the definitions of nuclear fission and fusion, uses of nuclear energy, and properties of gamma rays.
  • One participant suggests that nuclear reactions produce significant energy, indicating a belief in the strength of nuclear processes.
  • Another participant proposes that concrete may block gamma rays, while expressing uncertainty about the other options.
  • Some participants recommend using external resources like textbooks or Wikipedia for further understanding.
  • A participant encourages the original poster to narrow down answers to a maximum of two options for better clarity.
  • One comment reflects a light-hearted tone regarding the situation, indicating a mix of seriousness and humor in the discussion.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the answers to the worksheet questions, and multiple viewpoints and uncertainties are present regarding the correct responses and understanding of nuclear concepts.

Contextual Notes

Some questions may depend on specific definitions or interpretations of nuclear reactions and radiation, which are not fully explored in the discussion. There are also indications of missing assumptions or prior knowledge that could affect understanding.

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!
