yes from - to +

No. By convention Electricity current moves from positive to negative.
Charge of electrical particle was abritrarilly given.
an electron was given negative charge and proton was given positive charge.
The signs could have been assigned the other way around as well=Its arbitrary.
Then come the definition of charge= the exact definition of what a charge really is still remains a mystery in the world of Physics.
Electricity is considered as the flow of negative charge=why not consider it as the flow of positive charge?
Again its a matter of convention.

There is confusion here due to a convention that was adopted in the 1700's. At that time, scientists thought that current (electric charge in motion) move from the positive terminal to the negative. Hence, all our schematic diagram symbols that depend on polarity (direction of current flow) indicate the direction of flow point from the positive to the negative. It was over 100 years later that people came to discover that current flow was really made up of moving electorns - negatively charged particles - hence electricity moves from negative to positive terminals. But we still use the convention that current flows from positivie to negative and electrons move from negative to positive.

Electricity flows from a positive terminal to a negative terminal in most practical applications (like a battery)

since you used the word "run" i assume you are talking about the behavior of the electrons.
the assumed direction of the current is typically from High potential to Low potential. The direction of the electron flow is ALWAYS opposite to the direction of the current flow.
If you had a resistor connected to a battery, the flow of current would be out of the + side of the battery into the top of the resistor (Higer potential) out the bottom of the resistor into the - side of the battery (Lower potential). The flow of the electrons is exactly the opposite.

Only on British cars does the polarity go negative to positive. Just about all other electronics I've fooled with goes positive to a common negative ground, what the British call "earth".

If there is a deficiency of electrons on one point it has a positive potential, other electrons will flow to that point.

No.Electrons run from -ve to +ve terminals.electicity from +ve to -ve which is called conventional current.Due to flow of electrons,an electronic current is generated which flows from -ve to +ve.But the conventional current is only taken into account.

electrons flow from - to + and holes (check on wiki if you dont know what these are) flow from + to -.
so electron current goes - to +

no! it runs the other way round
