Nucleal, also known as nuclear, is a term used to describe anything related to the nucleus, the central part of any atom. In scientific literature, other synonyms for nucleal can be found, including atomic, corpuscular, and subatomic. Atomic refers to the smallest possible division of an element and is often used interchangeably with nucleal. Corpuscular refers to particles that make up matter, whereas subatomic relates to anything that exists on a smaller scale than an atom, such as protons, neutrons, and electrons. These terms are often used in conjunction with nucleal when discussing the fundamental building blocks of matter.
