Atomic Number

Atomic number is the number of protons found in the nucleus of an atom. It is a fundamental concept in chemistry and physics, as it determines the chemical properties and behavior of an element. In space and astronautical engineering, the atomic number is important in understanding the behavior of atoms and molecules in various environments, such as in the vacuum of space or in the extreme conditions of a rocket engine. The atomic number is also used in the design and operation of nuclear reactors and other space propulsion systems. Additionally, the atomic number is used in the analysis of cosmic rays and other high-energy particles that are encountered in space.
