elementI

Elementi (elements) are fundamental constituents across diverse disciplines, including chemistry, mathematics, computer science, and linguistics. In chemistry, an element is a substance that cannot be broken down into simpler substances by chemical means. Each element is characterized by a unique atomic number, equal to the number of protons in its atoms. Elements occur naturally or are synthesized, and they are organized in the periodic table, which groups elements by properties such as metal character, reactivity, and electron configuration. As of now, 118 elements have been confirmed, with symbols used as shorthand.

In mathematics, an element is a member of a set. For example, 3 is an element of the set {1,2,3}. The concept underpins set theory, relations, and functions.

In computer science and data structures, an element is an individual item stored within a collection, such as an element of an array, list, or set. Elements may be of various data types and are accessed by indices or keys.

In logic and philosophy, elements can refer to fundamental components of arguments or systems, such as axioms or primitive notions.

The term derives from Latin elementum and Greek elements; historically, the concept has evolved from classical elements in ancient philosophy to modern scientific classifications, culminating in the wide-ranging use of the term to denote basic constituents across domains.
