There are particles within the atom that are charged. Protons have a positive charge, while neutrons have a neutral charge(in other words they have no electrical charge). If you take a look at the website below, the blue circles in the centre represent neutrons, with no charge, and the red circles are protons, with a positive electrical charge. The gray spheres orbiting around the nucleus(centre of the atom with most of the mass) represent electrons, which have a negative charge and weigh about 1/2000 of the mass of a proton/neutron. visitthis site http://upload.wikimedia.org/wikipedia/commons/thumb/e/e1/Stylised_Lithium_Atom.svg/180px-Stylised_Lithium_Atom.svg.png
Potential energy is a energy stored within a system as a result of the position or configuration of the different parts of that system.The types of potential energy are gravitational potential energy, which is energy due to height, and elastic potential energy, which is energy involved with a stretched or compressed spring.
The particle that has the opposite charge of an electron is the proton. The electron has a charge of -1 while the proton has a charge of +1. (Though they have equal - but opposite - charges, the proton is about 1836 times more massive than the electron.) It might be worth mentioning that the antiparticle of the electron, the positron, also has a charge of +1. And it (the positron or antielectron) has a mass identical to the electron's. (An antielectron, the positron, will combine with an electron when the pair are at low energy in an annhilation event. Both particles will have their masses converted into energy.)
When a negatively charged rod approaches an electroscope, it induces a separation of charges within the electroscope. Electrons in the electroscope are repelled by the negative charge of the rod and move to the opposite end of the electroscope, leaving a net positive charge at the top. This gives the electroscope a positive charge, even though the initial influence was negative.
No, a charged particle will experience a force when moving through a magnetic field as long as it has a non-zero velocity component perpendicular to the field. This force is known as the magnetic Lorentz force.
Neutron: Mass: 1,00866491600(43) amu. Charge: neutral Electron: Mass: 5,4857990946(22)×10−4 amu. Charge: negative Proton: Mass: 1,007276466812(90) amu. Charge: positive
An atom is electrically neutral because the positive charge of its protons is balanced by the negative charge of its electrons. The number of protons (positively charged) is equal to the number of electrons (negatively charged) in a neutral atom.
The particle that carries the positive charge (a proton) is much more massive than the particle that carries the negative charge (an electron) The charges are equal in magnitude though of opposite polarity.
A current usually involves the movement of charged particles. ANY charged particle will do; though quite often, it is the electron (negative charge). Other options include holes (positive), and ions (positive or negative) in a solution.
Electric potential is like electric potential energy, except electric potential energy requires that you have at least two charged particles: one charged particle (can be considered to be stationary) to produce the electric field and another charged particle to be affected by that electric field. If both charged particles are positively charged, then when you move the nonstationary charged particle closer to the stationary charged particle, potential energy of the system increases, because the charged particles naturally want to repel. However, let's say you remove that nonstationary charged particle and are left with just the single charged particle. There is no more potential energy in the system, because there is no other charged particle to be acted upon by the electric field. However, the single charged particle still emits an electric field. This field is what creates "electric potential." Even though there is no second particle in the system, if you were to place a second particle into the system (let's call it a test particle), its potential energy would be equal to the electric potential multiplied by the charge of the test particle. U = kq1q2/r (electric potential energy with 2 charges, where the 0 of potential energy is infinitely far away) V = kq1/r (electric potential requiring only 1 charge) V = U/q2 (electric potential is potential energy without the second charge) U = Vq2 (electric potential energy is electric potential multiplied by second charge) There is also a concept called gravitational potential, where it's gravitational potential energy divided by the test mass. It can be a negatively charged particle. In that case, electric potential decreases as you get closer to the negatively charged particle. Even though electric potential decreases, if you have two negatively charged particles, electric potential energy increases as you move the 2nd negative charge closer to the first charge. This is because multiplying 2 negative charges makes a positive: U = k(-q1)*(-q2)/r = kq1q2/r (assuming q1 and q2 are the charge magnitudes) So in this case, it's a little weird because that's how the math works. Nature has a tendency to reduce potential energy, but potential is different and doesn't work the same way. However if the test charge was positive, the sign of electric potential energy will be the same as electric potential with respect to location. V = k(-q1)/r = -kq1/r U = k(-q1)(q2)/r = -kq1q2/r Potential energy is not the same as potential! They are related, but don't get them confused. Energy is measured in Joules. Potential is measured in Volts. Completely different units. Volts = Number of Joules / Number of Coulombs. Electric Potential = Electric Potential Energy / Charge of Test Particle

Yes, matter is typically charge-neutral because it contains equal numbers of positively and negatively charged particles (protons and electrons, respectively). This balance of charges allows matter to maintain a neutral overall charge.
the electron, though any charged particle can create a flowing current.

No, If you delete it first you sould not get charged. But you might be charged for receiving it though.
Why doesn't your laptop charge even though it's plugged in
The electrically charged particle in the ionosphere is called an ion. Ions are atoms or molecules that have gained or lost one or more electrons, resulting in a positive or negative charge. These ions play a crucial role in the electrical conductivity and plasma dynamics of the ionosphere.
