Facts and Info
The information that I am about to share with you is merely a sample of some of the wonders of the Universe. Many more facts, including detailed information on each planet in the solar system can be found in the book George's Secret Key To The Universe.
Particles
- Elementary particles are the smallest possible things that cannot be divided up into smaller particles. Examples include the electrons, which carry electricity, and the photon, which carries light.
- An atom is not an elementary particle because it is made of electrons going around a nucleus in the centre, like the planets go around the Sun. The nucleus is made of protons and neutrons packed tightly together.
