That's kind of a stupid question, they all do
it depends on the cpu. I program microcontrollers that have as few as 8 pins, cpu's on motherboards have many more as they are required to interface with external devices such as memory busses. usually in excess of 200. more modern processors don't have pins, they have contact points which meet contact points on the mainboard. pins are a relative point of discussion but not necessarily factual.
Yes. The pins that connect the CPU to the motherboard are made of gold.
yes
LGA : Land Grid Array <== pins are in the socket, no pins are attached on the CPU, only pads. PGA: Pin Grid Array <== pins are attached on to the socket, the socket has some sort of "holes" that hold the processor
4 pins
LGA
No. They both have totally different pin sizes and amount of pins. Socket AM2 has a lot more pins, socket a has 462 pins.

LGA Sockets, most often used by Intel place the CPU Pins in the motherboard instead of on the CPU. For your viewing pleasure: PGA Sockets place the pins on the CPU BGA Sockets solder the CPU to the motherboard, and use rounded beads instead of obvious pins Slot Sockets look and behave in a manner similar to PCI, and have card slot arrays instead of individual pins DIP Sockets place the pins only on the outer edges of the chip. These are old and crude. PLCC Sockets have metal fins on all four sides, with a small chip that fits inside. This chip has receiving points that are flat against the chip, giving them an appearance similar to that of a game cartridge. (Some New BIOS chips still use this. Little chip nested inside of a brown plastic square) Think thats about it, though I'm sure there's a socket type I missed somewhere!
