You need basically two things: a complete, closed-loop conductive path and an electro-motive force, that is, a voltage. Check out this picture for a simple circuit containing a battery, two wires, and a light bulb: http://www.bbc.co.uk/schools/ks3bitesize/science/images/sci_dia_52.gif. The wires and bulb complete the conductive path from, and returning to, the battery.
Free electrons. These can be in the form of valence electrons in a crystalline structure of a metallic solid. A good example is Copper, which has a high conductivity due to it's free electrons.
Initial velocity (in air/vacuum) or/and electric potential.
An Electro-Motive Force EMF such as a battery.
The most common way to move electrons from the air is by magnetism, which is produced By a generator. This force produced by the generator is called Electromotive Force (EMF)
An electric field.
The need for EMF
Voltage and conductivity.
In order to have the electricity or the flow or electrons going around the circuit, the circuit must be closed. If it is not closed then electrons cannot flow.
No. For electrons to flow, you need a current.
well, current is the movement of free electrons so if you break a point in the wire you effectively stop the electrons from flowing as the electrons need to be touching each other in order to pass on energy or charge. The reason why if there is a gap in the circuit the electrons dont just jump it is because of resistance of air as the electrons in air are not free to flow they are not conduction electrons unlike in a metal such as copper wire.
Conducting materials readily give and receive electrons from one atom to another. Electric current is actually the flow of electrons, so if it's difficult for the electrons to move, there will little or no current flow.
You don't need a "law of current" from that, but you can derive it from Ohm's Law.

Without conductors, electrons do not flow where you want them to flow. An electrical circuit is a flow of electrons.
To Complete the Circuit To allow the Electrons to Flow from the conducting material and to avoid the shocks plastics are used
electrons need a closed loop called what in order to move?
A "circuit".
Electrons need to be able to flow from each part of the circuit to the next, and they donβt flow easily through air. This is why wires are used. They have a smaller resistance than air, and so the electrons can flow smoothly.

Flowing electrons makes electricity (they flow from negative to positive. ). You need a circuit or a path for the electrons to move through, a power source like a battery or a generator, and something to use the electricity, like a light bulb...
Electricity is the flow of electrons.Hence it requires a path containing free electrons in order to flow.
Your question is not clear. A current is generated when a group of electrons flow through a conductor, and this happens when there is a potential difference between the 2 ends of the conductor. If you want to know how can we start the flow of electrons it is by creating a potential difference in between the 2 ends of the conductor.
yes it need ion to flow
