Science >> Chemistry for Kids The atom is the basic building block for all matter in the universe. Atoms are extremely small and are made up of a few even smaller particles. The basic particles that make up an atom are electrons, protons, and neutrons. Atoms fit together with other atoms to make up matter. It takes a lot of atoms to make up anything.What are facts about atom?

Today scientists understand that protons and neutrons are made of even smaller particles called quarks which are tied together...What are facts about atoms?
Interesting Atoms Facts: Atoms contain a dense nucleus surrounded by a cloud of electrons, which contain a negative charge. The interior of the nucleus contains positively charged protons, and almost all atoms' nuclei (with the exception of hydrogen-1) contain neutrally charged neutrons.What is the diagram of an atom?
Basic Diagram of an Atom. Most of an atom is just empty space and consists of a positively charged nucleus of protons and neutrons surrounded by a cloud of negatively charged electrons. The center of an atom is the nucleus and one or more electrons surrounding the nucleus.
