In chemistry, an element symbol refers to the one- or two-letter abbreviation for a chemical element, though the term also can be applied to alchemical symbols. Key Takeaways: Element Symbol Definition An element symbol is a one- or two-letter abbreviation for a chemical element name. When ...
An element is a fundamental item that can't be easily broken into smaller pieces. In chemistry and physics, an element is a substance that can't be broken down by non-nuclear reactions. In computing and mathematics, an element is a distinct piece of a larger system or set. Elements in ...
in his 1665 bookThe Sceptical Chymist, he proposed that an element was a substance that could not be reduced (‘analysed’) to something simpler. But Boyle’s definition only tells youwhenyou have an element, and not what an element is and what distinguishes one from another. And it is h...
Definition of an atom: Atomsare the smallest particles of anelementthat have the chemical properties of that element. Atoms are therefore extremely small (thehydrogenatom is the smallest) and are sometimes described as the "basic building blocks of matter". ...
Hijmans considers the evolution of the concept of element in the history of chemical and concludes that chemists have developed an increasingly generic and flexible definition of element that encompasses "both a stable portion of matter and a conceptual tool used to d...
