Chemical Element
In space and astronautical engineering, a chemical element is a substance that cannot be broken down into simpler substances by chemical means. Chemical elements are the building blocks of matter and are essential to the composition of all known materials, including those used in space technology. Each element is defined by the number of protons in its nucleus, known as its atomic number. The properties of an element are determined by the arrangement of its electrons in its atomic structure. In space and astronautical engineering, the study of chemical elements is crucial for understanding the behavior of materials in extreme environments, such as those encountered in space. The properties of elements are used to design and develop materials for spacecraft, satellites, and other space technologies.
