Los cuatro elementos sublunares: fuego, agua, aire y tierra, según un grabado de 1472. Los cuatro o cinco elementos de la naturaleza —habitualmente, el agua, la tierra, el fuego y el aire, a los que suele añadirse la quintaesencia o éter — eran, para muchas doctrinas antiguas, los constituyentes básicos de la materia y explicaban el ...
The periodic table of the elements by WebElements. The periodic table is an arrangment of the chemical elements ordered by atomic number so that periodic properties of the elements (chemical periodicity) are made clear. Explore the chemical elements through this periodic table.
118 chemical elements have been identified and named officially by IUPAC. A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z ). [1]
t. e. A chemical element is a chemical substance that cannot be broken down into other substances by chemical reactions. The basic particle that constitutes a chemical element is the atom. Chemical elements are identified by the number of protons in the nuclei of their atoms, [1] known as the element's atomic number. [2] .
