6.06: Nuclear Reactions Worksheet—Assignment Template Part 1 (20 points)

Describe how your answers changed on the survey from the beginning of the lesson to the end.

Explain which parts of the lesson helped change your mind.
If your answer did not change, explain which parts of the lesson supported your original opinion.
WRITE IN COMPLETE SENTENCES.

Your paper must be written in your own words, combining information from all the sources you use. Refer to the lesson for help on using quotations on small amounts of text.

Statement
How my answer changed
Part of the lesson or other evidence that changed my mind / supported my original answer
The wastes from nuclear power plants are very toxic.

Nuclear power plants produce less air pollution than power plants that use fossil fuels.

Nuclear power plants are safe.

The benefits of nuclear power outweigh the risks.

Part Two (20 points)
Design a diagram, sketch, or other model to show changes in the nucleus of an atom during nuclear fission and fusion. Include a short description and a way to compare the amounts of energy released in each event. Here is an example using alpha decay.

Example
In alpha decay, the parent nucleus loses an alpha particle, which is two protons and two neutrons. The new nucleus is smaller than the original. Alpha particles have a high amount of kinetic energy and can damage skin and living tissue. But, they are easy to shield against and can be stopped by paper or fabric.

Fission

Diagram, sketch or model

Description:

Fusion

Diagram, sketch or model:

Description:

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance

chemical properties: properties of a substance relating to the chemical nature and reactivity of the substance

assuming that your periodic table has eighteen columns, you should highlight   the four elements in the third column from the left of the table.

neutral atoms of elements after calcium contain d electrons. the energy of d orbitals of a particular main shell lies between the energy of the s and p orbitals of the next main shell. for example, electrons in the have energy higher than those in the orbital while lower than those of the orbital.

by the aufbau principle, electrons fill orbitals one at a time, starting from those of the lowest energy. the orbital is therefore filled right after orbitals and before orbitals.  

potassium has electron configuration and calcium . the s orbital of a main shell holds a maximum of two electrons. the next element would thus have the electron configuration and satisfy the requirements.

a neutral atom of the element contains three electrons on top of the most recent noble gas element. it should thus be placed in the third column of the periodic table. both scandium and yttrium would satisfy the conditions. an aufbau diagram indicates that the 4f orbital is filled before the 5d. however, it appears that exceptions exists for both lanthanum and actinium. neutral atoms of the two d-block elements also demonstrate the and should be highlighted as well.

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.
