The term "more cathodic" refers to the tendency of a substance to attract electrons and become negatively charged. There are several synonyms for this term, including more reduction potential, more electron-attracting, more negative, and more reducing. These descriptors are commonly used in chemistry and electrochemistry, where they help elucidate the behavior of various substances in chemical reactions. By measuring the electron potential or reduction potential of different materials, scientists can predict how they will react with other substances and how they will contribute to the overall electrochemical behavior of a system. Ultimately, these terms reflect our understanding of the underlying nature of electrons and electricity, helping us to better understand and harness these fundamental forces of nature.
