How many 120 V 20 amp receptacles are there?
2. There is a 20 amp 120 volt single recept or a duplex style. But the prong configurations are the same.
Why wouldn't a 2 prong plug fit in a 3 prong outlet?
The reason might be a voltage or amperage mismatch between the two devices. Plugs and receptacles are matched sets depending on the voltage and the amperage of the devices. The configurations are done in this manor to prevent the wrong voltages being applied to wrong plug in equipment.
Can you change a 2 prong plug with a three prong plug if you use a GFCI breaker?
NO - it is not safe to do that. A GFCI breaker is only a secondary safety device and your primary safety still depends on the earth wire in a 3-pin supply.
Is there an inexpensive and safe way to convert 2 prong outlets to 3 prong without rewiring your house?
You can convert your 2-wire ungrounding outlets to 3-wire grounding outlets by installing a GFCI receptacle in place of the 2-wire receptacle. The GFCI will be a 3-wire receptacle. In addition, if you replace the first receptacle in a series with a GFCI, you can protect all receptacles downstream of the first one by wiring them on the LOAD side of the GFCI. Once this is done, the 2-wire receptacles downstream may legally be replaced with 3-wire receptacles. They must be marked "No equipment ground", and there may not be an actual grounding conductor installed between the GFCI and the protected devices. You can easily convert a 2 prong to a 3 prong by just replacing the outlet. This will not give you the protection of a grounded outlet as there is no ground wire to connect. I know it is expensive but if you plan on staying in this home, have it rewired, for the safety of your family. The first thing u need to know is which wire is the neutral. If u know which is the neutral u can use that one for the ground also, consequently making a 2 prong into a 3 prong. I seen an electrician do this. Get a "neon tester." This is a neon bulb with two wires coming out of it. Take the screw that holds the cover plate onto the outlet off, and set it to the side. Then plug one wire from the tester into the right-side slot on one of the outlets, and one wire into the left-side slot. The tester should light up. (We did this to make sure the tester works. Sometimes they don't.) If it does, pull the wire out of the left-side slot and stick it into the screwhole. If it didn't light up, stick the wire back in the left-side slot then pull the wire out of the right-side slot and stick it in the screwhole. If it lit up on either occasion, you have a ground going to the box, and you can legally put a three-prong outlet in without rewiring. I tell you this because at one time, they used to wire houses this way--in places like the kitchen and bathroom you needed three-prong outlets, but in bedrooms you only need two-prong, so they'd use outlets and wiring that grounded the center screw. If you really NEEDED a grounded outlet, you bought one of those little 2-prong to 3-prong adapters and ran the screw through the tab to ground it. If you don't get a light on either position, don't put a grounded outlet there.

Can you still use single pole electrical sockets?
if you mean 2 prong sockets instead of the 3 prong ones no. they were illegal in usa in kitchens since 1960 have you ever seen a toaster with a grounded plug? they are illegal everywhere in the usa since 1981 now they are illegal to replace a broken 2 prong with a new 2 prong you SHALL run a ground wire and replace it with a grounded receptacle you can buy them in most stores. if you use it it will fail inspection and invalidate your fire insurance. you can also buy #18 100' extension cords that arent grounded. if you try to use a power saw with it chances are it wont cut thru a 2" board. light bulbs still use a single pole threaded Edison socket so yes you can with light bulbs. there are still Edison receptacles in some old houses. they were replaced with the prong ones without grumbles because its harder to stick your fingers in em and most people don't like the tingle.

This is a 2 prong polarized female. However a 2 prong unpolarized male will easily plug into a 2 prong polarized female. just not the other way around.?

Why would 3 prong plugs not fit into 3 prong outlets. This is a new home. All outlets only work on 2 prong plugs.?
This is very strange indeed. All modern houses in USA would have 3-prong outlets. I can't see how it could pass an electrical inspection. Check with the local agency who does inspections. Check your electric panel and look for an inspection sticker. I have encountered receptacles that are very hard to use because one or more of the pin slots (I don't know what else to call them) are way too tight. There is no easy remedy for this problem except to press hard to get the plug into the receptacle or replace the receptacle with one of a better quality. There are also child protective receptacles that require that two or three of the pins be pressed in at the same time or none of them will go. If the plug is just slightly off true it won't go.
How do you test for groung on a two prong outlet?
Buy a tester. They are very cheap and will tell you at a glance if the outlets are wired correctly. The only other way is to remove the outlet and look see. But if it is a 2 prong outlet with no ground hole then it does not have a ground.
