The mass (weight) of an electron is approximately equal to 1/1836 that of a hydrogen atom, which has one electron and one proton, so an electron is 1/1836th the size of a proton. Electrons carry a small electronically negative charge. In this model, electrons are in constant motion around the center of the atom.
The Nintendo 3DS costs around $169.99 USD. At launch, it was $249.99 USD, but the price dropped on August 12, 2011. However, that's just Nintendo's suggested retail price, so you might get lucky and find a 3DS for an even cheaper price somewhere else. The Nintendo 3DS XL is larger than the 3DS. It has not just larger screens but also a thicker overall size with bigger buttons and Circle Pad, plus a longer lasting battery. This is why it's a little more expensive than the 3DS, at around $199.99 for a basic model. Nintendo consoles can be purchased from variety of places but you'll notice that ones bundled with games or special cases will cost a little more than $169.99.
