Which statement is always true when nuclear fusion occurs?(1 point)

The number of protons in the resulting nucleus is double that of a starting nucleus.

The combined number of protons and neutrons remains constant.

The number of protons in the resulting nucleus is less than in each starting nucleus.

The total number of protons and neutrons in each nucleus remains constant.

Use the equation to answer the question.

2/1H+ 2/1H→ 4/2H+energy
Which statement best describes the mass numbers of the atoms in the reaction?

There is one atom with a mass number of 2.


There is one atom with a mass number of 1.


There are two atoms with mass numbers of 1.


There are two atoms with mass numbers of 2.
.

Why would placing two very strong magnets in the middle of two separate balloons provide a good model for nuclear fusion?(1 point)

Some nuclei repel each other and some attract each other, just like two sides of a magnet.

The nucleus is very large compared to the rest of the atom, just like the balloon surrounding the magnet.

The positive charges of the nuclei make it difficult for the nuclei to join, just like the balloons keep the magnets apart.

If the atoms combined, then it would destroy both of them, just like the balloons would be destroyed.


How is the mass number calculated for an atom involved in nuclear fusion?


It is the number of neutrons.
It is the number of electrons
It is the number of protons plus electrons.
It is the number of protons plus neutrons.

Which change will always take place in nuclear fusion?


A nucleus with a greater mass than any of the reactants will be produced.


The total charge will be greater than before the fusion took place.

Respuesta :

The characteristics of the nuclear fusion reaction allow finding the correct answers are:

1)  The combined number of protons and neutrons remains constant.

2) There are two atoms with mass numbers of 2.

3) The positive charges of the nuclei make it difficult for the nuclei to join, just like the balloons keep the magnets apart

4) It is the number of protons plus neutrons

5) A nucleus with a greater mass than any of the reactants will be produced

Nuclear fusion is a process in which light nuclei unite to form a heavier nucleus.  This occurs because the energy of the lighter nuclei is greater than the energy of the heavier nuclei, therefore the energy total of the new nucleus is less than the energy of the constituents.

In this exercise there are a series of questions about nuclear fusion

1) Two nuclei unite as the number of protons and neutrals behaves.

In fusion reactions, the number of protons and neutrons in the initial nuclei combine to form a heavier nucleus, therefore the new combination of protons and neutrals remains constant.

When reviewing the statements the correct one is:

The combined number of protons and neutrons remains constant.

2) Ask how many nuclei each mass number of the reaccition

            [tex]^2_1H \ + ^2_1H\ -> \ ^4_2H + energy[/tex]H

The mass number of the nuclei is written in the upper left

Therefore in the reaction there is

  • Thera are 2 Atoms with mass number 2
  • There is 1 Atom with mass number 4

When reviewing the statements, the correct one is:

There are two atoms with mass numbers of 2.

3) in this case the magnets represent the nucleus that has a positive charge and repel each other, also the volume of the nucleus of the atom is much smaller than the volume of the atom.

Therefore, for the reaction to occur, there must be an external force that brings the nuclei closer until the strong interaction has a significant value.

When reviewing the statements, the correct one is:

The positive charges of the nuclei make it difficult for the nuclei to join, just like the balloons keep the magnets apart

4) The mass one atom is the sum of more of the protons plus the mass of the neutrons since the electrons are much lighter

The correct one is:

A nucleus with a greater mass than any of the reactants will be produced

5) When a nuclear fusion reaction occurs, the mass of the resulting nucleus is greater than the mass of the reactants.

When reviewing the statements, the correct one is:

A nucleus with a greater mass than any of the reactants will be produced.

In conclusion with the characteristics of the nuclear fusion reaction we can find the correct answers are

1)  The combined number of protons and neutrons remains constant.

2) There are two atoms with mass numbers of 2.

3) The positive charges of the nuclei make it difficult for the nuclei to join, just like the balloons keep the magnets apart

4) It is the number of protons plus neutrons

5) A nucleus with a greater mass than any of the reactants will be produced
