original: Solid metallic hydrogen consists of a crystal lattice of atomic nuclei (namely, protons), with a spacing which is significantly smaller than a Bohr radius.
simplifications: Solid metallic hydrogen consists of a crystal lattice of atomic nuclei with a spacing which is significantly smaller than a Bohr radius. Solid metallic hydrogen is made of a crystal lattice of atomic nuclei with a spacing smaller than a Bohr radius. Metallic hydrogen consists of protons with spacing smaller than a Bohr radius. Solid metallic hydrogen consists of a crystal lattice of atomic nuclei. Most are protons. The spacing is significantly smaller than a Bohr radius. Solid metallic hydrogen is a crystal lattice of atomic nuclei (protons), with a much smaller spacing than a Bohr radius. Solid metallic hydrogen is made of a crystal lattice of atomic nuclei (namely, protons). It has a spacing that is much smaller than a Bohr radius. Solid metallic hydrogen is a symmetrical three-dimensional arrangement of atomic nuclei. Solid metallic hydrogen has a crystal lattice atomic nuclei. The spacing is smaller than a Bohr radius. Solid metal hydrogen consists of an atomic nuclei (i.e. protons) crystal lattice with a spacing smaller than a Bohr radius Solid metallic hydrogen is made up of a crystal lattice of atomic nuclei (namely, protons), with a spacing which is really smaller than a Bohr radius.
