It is notable that although most stars, including the Sun, generate energy over most of their lives by fusing hydrogen into heavier elements, such fusion of light hydrogen (protium) has never been successful in the conditions attainable on Earth. (39 words)

Example sentences (12)
A molecule of heavy water has two deuterium atoms in place of the two protium atoms of ordinary "light" water.
Explanation Deuterium is an isotope of hydrogen whose nucleus comprises both a neutron and a proton ; the nucleus of a protium (normal hydrogen) atom consists of just a proton.
It is notable that although most stars, including the Sun, generate energy over most of their lives by fusing hydrogen into heavier elements, such fusion of light hydrogen (protium) has never been successful in the conditions attainable on Earth.
Like the water-cycle in Earth's weather, such heating processes may enrich deuterium with respect to protium.

Since the atomic number of hydrogen is 1, a hydrogen ion has no electrons and corresponds to a bare nucleus, consisting of a proton (and 0 neutrons for the most abundant isotope protium 1 1 yes ).
The analysis of deuterium/protium ratios in comets found results very similar to the mean ratio in Earth's oceans (156 atoms of deuterium per million hydrogens).
The deuterium in heavy water has a very much lower absorption affinity for neutrons than does protium (normal light hydrogen).
The name refers to examination of protons as they occur in protium (hydrogen-1 atoms) in compounds, and does not imply that free protons exist in the compound being studied.
