    List of chemical elements. 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]

  4. Periodic table - Wikipedia

    en.wikipedia.org/wiki/Periodic_table

    The periodic table, also known as the periodic table of the elements, is an ordered arrangement of the chemical elements into rows ("periods") and columns ("groups"). It is an icon of chemistry and is widely used in physics and other sciences.

  5. Nucleon - Wikipedia

    en.wikipedia.org/wiki/Nucleon

    In physics and chemistry, a nucleon is either a proton or a neutron, considered in its role as a component of an atomic nucleus. The number of nucleons in a nucleus defines the atom's mass number (nucleon number) . Until the 1960s, nucleons were thought to be elementary particles, not made up of smaller parts. Now they are known to be composite ...

    Electrons and a compact nucleus of protons and neutrons. Atoms are the basic particles of the chemical elements. An atom consists of a nucleus of protons and generally neutrons, surrounded by an electromagnetically bound swarm of electrons. The chemical elements are distinguished from each other by the number of protons that are in their atoms.

  8. Atomism - Wikipedia

    Atomism (from Greek ἄτομον, atomon, i.e. "uncuttable, indivisible") [1] [2] [3] is a natural philosophy proposing that the physical universe is composed of fundamental indivisible components known as atoms . References to the concept of atomism and its atoms appeared in both ancient Greek and ancient Indian philosophical traditions.

  9. Atomic nucleus - Wikipedia

    en.wikipedia.org/wiki/Atomic_nucleus

    The atomic nucleus is the small, dense region consisting of protons and neutrons at the center of an atom, discovered in 1911 by Ernest Rutherford based on the 1909 Geiger–Marsden gold foil experiment. After the discovery of the neutron in 1932, models for a nucleus composed of protons and neutrons were quickly developed by Dmitri Ivanenko [1 ...
