An atom is comprised of a nucleus of protons and neutrons, and layers of 'shells' in which the electrons revolve around the nucleus. An element is defined by the number of protons in the nucleus while the number of electrons on the outer shell define an atoms group on the Periodic Table. Then the number of neutrons is added to the number of protons to define the atomic weight of the atom.
Electrons have the least amount of energy compared to protons and neutrons. Protons and neutrons have similar amounts of energy in an atom, as they are found in the nucleus and contribute to the majority of the atom's mass.
A standard atom of Silver (Ag) contains the following amounts of sub-atomic particles: Electrons: 47 Protons: 47 Neutrons: 61 Neutrons = Mass Number - Protons
Oxygen has 8 electrons and protons. The number of neutrons is different for each isotope: Number of neutrons = Atomic mass of the isotope - Number of protons
Promethium has 61 protons and electrons; For each isotope the number of neutrons is different. Number of neutrons = Mass number of an isotope - 61
Technetium has 43 protons and 43 electrons. For each isotope the number of neutrons is different. Number of neutrons = Mass number of an Tc isotope - 43
Electrons carry a negative charge, protons and neutrons do not.
These particles are: protons, neutrons and electrons.
Nickel has 28 protons and electrons; the number of neutrons is different for each isotope.
Uranium isotopes have 92 protons and electrons; the number of neutrons is different for each isotope.Number of neutrons = Mass number - Number of protons
Cl-37 : 17 protons , 20 neutrons , 17 electrons Compare with Cl-35 ; 17 protons , 18 neutrons, 17 electrons. These are two different and common isotopes of chlorine. Remember 'Different isotopes have a different number of neutrons'. Chemically they react the same.
