A report on Atom, Proton, Atomic nucleus, Hydrogen and Deuterium
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.- Atomic nucleus
Deuterium (or hydrogen-2, symbol or deuterium, also known as heavy hydrogen) is one of two stable isotopes of hydrogen (the other being protium, or hydrogen-1).- Deuterium
The nucleus of a deuterium atom, called a deuteron, contains one proton and one neutron, whereas the far more common protium has no neutrons in the nucleus.- Deuterium
One or more protons are present in the nucleus of every atom.- Proton
Every atom is composed of a nucleus and one or more electrons bound to the nucleus.- Atom
The nucleus is made of one or more protons and a number of neutrons.- Atom
The diameter of the nucleus is in the range of 1.7 fm (1.7 m ) for hydrogen (the diameter of a single proton) to about 11.7 fm for uranium.- Atomic nucleus
Only the most common variety of hydrogen has no neutrons.- Atom
For the most common isotope of hydrogen (symbol 1H) each atom has one proton, one electron, and no neutrons.- Hydrogen
In previous years, Rutherford had discovered that the hydrogen nucleus (known to be the lightest nucleus) could be extracted from the nuclei of nitrogen by atomic collisions.- Proton
The nuclei of the heavy hydrogen isotopes deuterium and tritium contain one proton bound to one and two neutrons, respectively.- Proton
For example, between protons and neutrons to form [NP] deuteron, and also between protons and protons, and neutrons and neutrons.- Atomic nucleus
Oxidation of hydrogen removes its electron and gives H+, which contains no electrons and a nucleus which is usually composed of one proton.- Hydrogen
, the other stable hydrogen isotope, is known as deuterium and contains one proton and one neutron in the nucleus. All deuterium in the universe is thought to have been produced at the time of the Big Bang, and has endured since that time. Deuterium is not radioactive, and does not represent a significant toxicity hazard. Water enriched in molecules that include deuterium instead of normal hydrogen is called heavy water. Deuterium and its compounds are used as a non-radioactive label in chemical experiments and in solvents for -NMR spectroscopy. Heavy water is used as a neutron moderator and coolant for nuclear reactors. Deuterium is also a potential fuel for commercial nuclear fusion.- Hydrogen
For example, it requires only 13.6 eV to strip a ground-state electron from a hydrogen atom, compared to 2.23 million eV for splitting a deuterium nucleus.- Atom

The neutron is a subatomic particle, symbol or, which has a neutral (not positive or negative) charge, and a mass slightly greater than that of a proton.
Protons and neutrons constitute the nuclei of atoms.
Neutrons are required for the stability of nuclei, with the exception of the single-proton hydrogen nucleus.
The nuclei of the heavy hydrogen isotopes deuterium (D or 2H) and tritium (T or 3H) contain one proton bound to one and two neutrons, respectively.
