Quarks- any group of subatomic particles believed to be among the basic components if matter Quarks are believed to be the fundamental constituents of matter, and have no apparent structure. They are the particles that make up protons and neutrons, which make up the nucleus of atoms. Also, particles that interact by means of the…
Isotopes have the same number of protons, but different numbers of neutrons. This means that while the atomic number of an element will NEVER change…The MASS of the atom can change quite a bit depending on how many neutrons there are The number of protons in an atom is also called the “atomic number”. This…
Stars begin their lives as clouds of dust and gas called nebulae. The gravity of a passing star or the shock wave from a nearby supernova may cause the nebula to contract. Matter in the gas cloud will begin to coalesce into a dense region called a protostar. As the protostar continues to condense, it heats…
