The atomic number often is not included because the element name (or element symbol) also tells the number of protons. If the number of protons changes, then it becomes a different element. For example, helium will always have 2 protons; if you add a proton then it becomes lithium (Li).

As helium is cooled below its transition point, it has an unusual property of superfluidity with a viscosity approaching zero micropoises. In addition, liquid helium has extremelyhigh thermal conductivity. Helium Menu. Helium Page One.

You can compare H vs He on more than 90 properties like electronegativity , oxidation state, atomic shells, orbital structure, Electronaffinity, physical states, electrical conductivity and many more. Atomic Structure: All atoms consist of a nucleus which contains two types of subatomic particles - protons and neutrons. The nucleus is surrounded by a cloud of electrons at varying energy levels. These subatomic particles are composed of even smaller particles known as quarks which came together after the Big Bang around 13.7 million years ago.

have utilized the 4 He atomic beam to probe the He-C interaction and to study structure transition on a diamond C(111) surface [81]. The authors have traced the diffraction patterns for various azimuthal angles of the surface Brillouin zone of a diamond C(111) surface with incident energies E i = 63.2 and 17.3 meV. Helium atom {a particle} is the most stable creation. Helium atom as every composed quantum formation has two properties energetic semi-loop {strong force} and gravity semi-loop {weak force}.

Alpha decay happens when an atom is too big and needs to get rid of some mass. Beta decay is when a neutron turns into a proton or a proton turns into a neutron. Helium Atomic Structure www.grandunifiedtheory.org.il.
