Difference between Helium and Hydrogen atom

Helium vs. Hydrogen atom

Helium (from lit) is a chemical element with symbol He and atomic number 2. A hydrogen atom is an atom of the chemical element hydrogen.

Similarities between Helium and Hydrogen atom

Helium and Hydrogen atom have 21 things in common (in Unionpedia): Abundance of the chemical elements, Atom, Atomic orbital, Baryon, Chemical element, Deuterium, Energy level, Ernest Rutherford, Ground state, Half-life, Hydrogen, Interstellar medium, Isotope, Isotopes of helium, NASA, Niels Bohr, Nuclear reactor, Oxygen, Quantum mechanics, Solar wind, Tritium.

Abundance of the chemical elements

The abundance of the chemical elements is a measure of the occurrence of the chemical elements relative to all other elements in a given environment.
