อะตอม (กรีก: άτομον; อังกฤษ: Atom)

Atom (Greek: άτομον; in English: Atom) is the basic unit of matter consisting of a portion of the nucleus is very dense in the Center. Surrounded by a group of fog of electrons with a negative charge. Atomic nucleus consists of a Proton with a neutral Neutron, prachubuak power (except in the case of hydrogen-1, which is the only type of stable nuclide with no neutron.) The electrons of an Atom are attracted to the nucleus by the electromagnetic force. Similarly, A group of atoms can attract each other the formation as a molecule. Atoms that have the same number of protons and electrons are in a neutral condition, electrical. Otherwise, it might have a positive charge (because of the missing electron) or delete (because it has excess electrons), called ion atomic number with our assortment of proton and neutron in the nucleus. The number of protons defines the type of the chemical element and the number of the isotopes of the element type to indicate neutron [1]

Atom (Greek: άτομον; English: Atom) is the basic unit of matter. It consists of a dense nucleus at the center. Surrounded by a cloud of negatively charged electrons. The atomic nucleus contains positively charged protons and electrically neutral neutrons. (Except in the case of hydrogen-1, which is the only kind of stable nuclide with no neutrons) and electrons of the atoms are attracted to the nucleus by the electromagnetic forces. Likewise Groups of atoms can be attracted to each other to form a molecule. Atoms with the same number of protons and electrons is electrically neutral. Otherwise, it may have a positive charge. (For lack of electrons) or negative (because there are more electrons), which is called the atomic ions are classified by the number of protons and neutrons in the nucleus. Proton is indicative of the type of chemical elements. And neutron isotopes of elements that indicate the type [1].

Atom (Greek:). ά τ ο thermal ο ν; English: "He Atom) is the basic unit of substance "composed of nucleus density at the center.(except in the case of "hydrogen - 1), which is one kind of stable nuclide without neutrons). อิเล็กตรอนของอะตอม is attracted with the nucleus with electromagnetism. Likewise.Atoms with the number of protons and electrons rate the neutral electrical Otherwise, it may have a positive charge (because of the lack of electrons) or negative (because the electrons over).
