How does a battery make a light bulb glow?
The flow of electrons from the battery flow through the filament in the bulb causing it to get hot and glow thus producing light.
What particle does the battery help supply to the wire which helps light the light bulb?
Electrons.
What is the job of a wire in a torch?
To conduct the flow of electrons/electricity from the battery to the bulb and back.
Why must there be two connections to a batter and to a light bulb?
The electrons must go from the battery to the light-bulb, then come back again to the battery through the other connection. If there is only one connection, there will soon (within microseconds or so) be an accumulation of electrons that will repel any additional electrons - the current will stop flowing.
Are negative electrons converted into positive in the light bulb of a simple battery circuit?
No See the related link below.
What describes electricity flowing from a battery though a switch to a light bulb?
Circuit Electrons flow form the positive end of the battery through the wire connecting the positive terminal to a switch. The other end of the switch is connected to one terminal on the bulb, the other terminal of the bulb is connected to the negative end of the battery. No electrons (current) flows as long as the switch is open. Once the switch is closed and if the battery has enough voltage and current capacity to make the filament in the bulb glow, then the bulb emits light (together with wasted heat). If the switch is open, no current flows through the entire circuit and the bulb does not glow.
How are batteries connected in a flashlight?
The electrons from the battery go through the wiring to the bulb. Inside the bulb, they heat a tungsten wire so hot that it glows, giving off light.
The potential difference of a battery depends on having an excess number of electrons at the negative terminal and a deficient number of electrons at the positive terminal?
That is true but not very - the excess of electrons at the negative terminal is small. The important thing is that if you place a load (radio set, light bulb etc.) on the battery the electrons flow through the load and this movement is supported by energy supplied by chemical action in the battery.
Do electrons from a battery reach a bulb before it light?
No, electrons from a battery don't reach the bulb before it lights. An electric current is not simply a flow of electrons. Rather, an electron in a circuit will move only a short distance and then nudge another electron into motion, which will do the same thing with yet another electron. So while the current moves through the entire circuit, individual electrons do not unless it is left on for a very long time.

What characteristics of metals contribute to their ability to conduct electricity?
In covalent compounds the electrons are bonded to the atoms, so they cannot move outside the molecule. When ionic compounds like NaCl are dissolved in water, they produce positive and negative ions that can be attracted to the opposite terminal of a battery, so electrons flow off of the negative ions thru the wiring, thru the light bulb and back into the salt water and onto the positive ions. [Click on the related link to see the image] The circle with a wave inside represents a battery. In metals like Al and Cu, the electrons are not bonded to one molecule. They are free to move all around the wire. If you were to take the same light bulb, battery and electrodes and use a copper wire to connect the electrodes, the bulb would light. The voltage of the battery forces electrons on one end of the wire. This produces more electrons than protons in the metal wire. Since the electrons are free to move, electrons will move off the other end of the wire and thru the bulb, causing the wire filament in the bulb to get so hot that it glows.
