) In a nuclear reaction, which quantity is the same before and after the change? (1 point)
the number of alpha particles
the types of atoms
the total mass
the total number of protons
A) Why does the emission of an alpha particle always result in transmutation? (1 point)
The atom is converted to helium.
The number of protons in the atom changes.
The protons in the large atom change to neutrons.
Energy is released from the nucleus of the atom.
A) Which phrase describes radioactive decay? (1 point)
the triggering of one reaction by the products of another
the spontaneous emission of radiation
the splitting of a large nucleus into smaller nuclei
the joining of small nuclei into a larger nucleus
Question 4
Question 5
Question 6
A) Which option would be an appropriate model of nuclear fusion? (1 point)
sewing one piece of fabric to another
putting a puzzle together
mashing two marshmallows together
adding a drop of water to a glass of water
A) Which aspect must be taken into consideration when creating a model of radioactive decay?
(1 point)
There must not be any changes to the element in question.
There must be a way for unstable nuclei to become stable nuclei.
There must be a predictable and reversible change that occurs.
There must not be any particles or energy emitted from the nucleus.
A) How is fusion different from a simple chemical reaction? (1 point)
Energy is released in a fusion reaction, but it is absorbed in a chemical reaction.
The nuclei combine in a fusion reaction.
Atoms come together in a chemical reaction, but they are split in a fusion reaction.
The atoms are bound to each other by electrons in a fusion reaction.
Question 7
A)
Use the image to answer the question.
Which statement best describes the charged particles in the fusion reaction?
(1 point)
The nucleus with the greatest positive charge is on the left side of the reaction.
The nucleus with the greatest positive charge is on the right side of the reaction.
There are no charged particles because the positive and negative charges will cancel out.
There are no charged particles because these are all nuclei, which are neutral

Fission. In these an unstable heavy atom is divided into several lighter atoms with the release of energy, these lighter nuclei are more stable than the initial nucleus.

Fusion. Two light nuclei are close enough so that strong nuclear forces make them merge into a heavier nucleus, in this case energy is also live.

It is asked to make a selection of which are the correct statements, for the different questions

1) In a nuclear reaction the amount of protons remains invariant, the neutral ones can be released or absorbed

The correct answer: The total number of protons

2) A particula alpha is a nucleus with 2 protons, two neutrons, so it always changes from one element to another

The correct answer is: The number of protons changes

3) as described radioactive decay.

It is the process by which particles or radiation are emitted from the atomic nucleus

The correct answer is: Spontaneous emission of radiation

4) Fusion is a process by which two nuclei unite and a larger one is formed

The correct answer is: sew one piece of fabric to another and form a larger one

5) What to take into account when creating a disintegration model.

A mechanism must be created that allows the particle emission from the nucleus with the decrease of the total energy of the system

The correct answer is: There must be an unstable nucleus form in stable nuclei

6) Difference between fusion and chemical reaction

In the fusion other atoms are formed, in the chemical reaction the atoms remain unchanged

The correct answer is: The nuclei combine in a fusion reaction

7) How to describe the charged particles in the fusion

in a fusion reaction in general no charged particles are released, so all charged particles (protons are in the new nucleus

there is not image

The correct answer should be: There are no charged released

In conclusion with the characteristics of nuclear reactions lets find the results to the questions are:

1) The total number of protons

2) The number of protons changes

3) Spontaneous emission of radiation

4) Sew one piece of fabric to another and form a larger one

5) There must be an unstable nucleus form in stable nuclei

6) The nuclei combine in a fusion reaction

7) There are no charged released
