7 Ιουν 2024 · A chemical element is a substance that cannot be broken down by chemical means. Although elements aren't changed by chemical reactions, new elements may be formed by nuclear reactions. Elements are defined by the number of protons they possess.
What is an Element? An element is a pure substance consisting of only one type of atom which all have the same numbers of protons in their nuclei. The question of the conceptual nature of the term “element” represents a rather unique opportunity to examine the relationship that currently exists between chemists and philosophers of chemistry.
