WebThe atomic number or nuclear charge number (symbol Z) of a chemical element is the charge number of an atomic nucleus. For ordinary nuclei, this is equal to the proton number ( np) or the number of protons found in the nucleus of every atom of that element. The atomic number can be used to uniquely identify ordinary chemical elements. WebSep 16, 2015 · definition, so no, you cannot have an element without any protons. They would be exotic forms of matter though, and they wouldn't be the first. Chemical elements by definition are the smallest unit of a substance that still retains the substance's properties, not a particle with protons, neutrons, and electrons. rogers roadhouse ft worth
