If a proton moved from 0 V potential to 5 V potential would its potential energy increase or decrease?

Electric field points from high potential to low potential. Positive particles had tendency to follow electric field. If you are moving the particle against this tendency you are doing work, and this work give more potential energy to the particle.

What happens to potential energy when a proton is brought closer to an electron?
Protons all have positive charge, so they repel each other. It takes work to push two protons closer together, so you're putting energy into them (potential energy increases). If you let go, the potential energy is released when the protons fly apart; it becomes kinetic energy.
The process of positron emission results in a change to the atomic nucleus. Is that change a decrease of 1 or a decrease of 2 or an increase of 1 or is there no change?
In positron emission, atomic number decreases by one. That's because a proton in the nucleus of the element that is about to undergo positron emission changes into a neutron. This is beta plus decay, by the way. You'll recall that the atomic number of an element, which is that element's chemical identity, is determined solely by the number of protons in the nucleus. If we "lose" a proton because it changes into a neutron, atomic number will now decrease by one. Check out the links below to related posts.
How much work does the electric field do in moving a proton from a point with a potential of plus 140 V to a point where it is -80 V?
Work = (Charge)x(Voltage change). The Charge on a proton is +e. The change in voltage is (-80 V - 140 V) = -220V. So it is -220 eV. It is negative, because the proton has moved to a lower potential, and therefore gave up energy to the field.
What kind of proton causes a nuclear reaction?
All protons are identical. Any proton with sufficiently high energy can cause a nuclear reaction.

A proton is in an electric field and has an electric potential energy of 0.5 J What is the electric potential voltage that it experiences?
First off you know that when it says "Proton" you should know that its a Positive (+) Charged subatomic particle! Now You use the equation that says --> Volt = Electric Potential Energy / Q Volt = 0.5 / +1 (proton) Volt = 0.5
Why the stability decrease with increasing atomic mass?
Stability depends on to proton/neutron ratio; and this ratio increase with the atomic number.
What are the four types of potential energy?
Potential stands for the position. Hence potential energy is due to the position. Gravitational, electric potential, magnetic potential, elastic potential. If the energy is possessed during the motion it is said to be kinetic. So if a moving proton approaches a positively charged nucleus then it has to stand for an instant due to electrostatic repulsion. In that still position, the whole KE will be available as electrostatic potential energy.
What is the amount of energy gained by a proton accelerated through a potential difference of 50 V?
The charge of proton 'e' is 1.602 x 10--19 C. If it is subjected to a potential difference of 50 V, then the electrostatic potential energy gained by that proton will be 50 eV. To get the energy in joule, replace 'e' by 1.602 x 10 --19. Then, the required value is 8.01x10 --19 J eV is the unit of energy which will be more convenient while dealing with very very small amount of energy. 1 eV = 1.602 x 10 --19 J
Proton and an alpha particle are released from rest when they are 0.225 apart. The alpha particle has four times the mass and two times the charge of a proton. What is the max speed of the proton?
From energy conservation set the initial electric potential energy = to the electrical potential energy at an arbitrary separation (as they fly apart) + the kinetic energy of each particle. Next write alpha velocity in terms of proton velocity by requiring momentum conservation (total momentum is always zero because they started from rest). Next solve for proton velocity. By inspection see that the max will occur when the arbitrary separation distance ,used above, is infinite. This should give you an equation for max proton velocity in terms of proton mass & charge & initial separation & Coulomb constant. PS: If the proton speed is close to the speed of light you would have to solve the problem relativistically,to get a correct answer, but should still be doable using conservation of energy & momentum.
The mass of the parts is always the mass of the whole when looking at nuclear masses?
No. The nuclear attraction is so strong that there is a lot of (potential) energy involved; so if you join particles (like, a proton and a neutron), there will be a significant difference of energy, and therefore of mass. Usually less than 1%, but quite noticeable.No. The nuclear attraction is so strong that there is a lot of (potential) energy involved; so if you join particles (like, a proton and a neutron), there will be a significant difference of energy, and therefore of mass.
