Neurons send messages electrochemically and all chemicals in the body are electrically-charged. When neurons inside the body are electrically-charged, they are called ions. When a neuron is at rest, or not electrically-charged, the inside is negative and the outside is positive.

It is the membrane potential of a neuron at rest?
Yes,the membrane potential of a neuron is at rest because it is the difference in electrical charge between inside and outside a resting neuron.
What is a sudden electrical charge in a neuron membrane is?
Yes.
Which condition is a neuron in when the outside of the neuron has a net positive charge and the inside has a negative charge?
resting potiental
When a neuron's resting potential is occurring the neuron is what charge on the inside?
resting potiental
What is inside a polarized neuron?
There is electrical potential difference between out side of the cell and inside of the cell, in case of the polarized neuron. This electrical difference is lost in case of depolarization. That is what can be said roughly.
What condition is neuron in when the outside of the neuron has a net positive charge and the inside has net negative charge?
This is called the resting potential (inactive state) of the neuron. However, when a neurotransmitter binds to receptors, electrical stimulus is applied, etc. to induce an opening of ion channels in the membrane of the neuron, positive ions rush into the neuron from the outside to the inside, and result in a sharp increase of the positive charge density (due to more positive ions) inside the neuron. Beyond a certain threshold, this can induce the creation of an action potential, causing the neuron to fire. After the action potential is created, and the neuron fires, there is a short refractory period where the neuron cannot be fired again due to stimuli, when positive ions are pumped back out of the neuron, negative ions are brought into the neuron, and then the ion channels close, leaving the neuron in a polarized state, and returning it to a resting potential.
How there can be electrical charge inside matter even if the matter shows no electrical forces?

What is the tiny electrical charge that exists when a neuron is neither receiving nor sending information?
a resting potential
What is the difference in electrical charge across the cell membrane of a resting neuron is called?
This is the definition of "resting potential".
What is a subatomic particle having zero charge found in the nucleus of an atom?
This particle is the neutron.
What is the state when an electrical charge of a neuron is said to be at a resting potential?
The resting potential is the normal equilibrium charge difference (potential gradient) across the neuronal membrane, created by the imbalance in sodium, potassium, and chloride ions inside and outside the neuron.
Explain how a neuron enter a state of depolarization?
At rest, a neuron is highly polarized -- a significant electrical charge difference exists between the inside and the outside (poles) of the cell. This polarity is what allows the cell to quickly respond to triggering events and do work, similar to the charge in a battery. A neuron de-polarizes when something reduces that charge difference, typically when pores in the cell membrane are unblocked, allowing charged ions to flow. Technically, a reduction of even a single electron of polar charge is a "depolarization". This can occur by dozens of mechanisms. However, the usual process is: (1) a neuron is polarized, (2) an electrical signal traveling inside the neuron changes the internal membrane charge just enough to cause voltage-sensitive pores to open, which (3) allows a massive influx of charged ions from outside the cell. This now depolarized cell recovers its resting polarity quickly through a reverse flow of electrons and via ion pumps in the membrane.
