05 Feb 2024 Hydrogen (H2)
H2 Is the chemical element with the lowest atomic mass. H2 is usually present as molecular hydrogen. Thermal activation causes H2 to decompose into atomic hydrogen 2H. In this form, hydrogen is very reactive and well suited to the reduction of metal oxides such as tin or copper oxides. An important disadvantage is that hydrogen between 4% and 77% is explosive under atmospheric conditions, making complex safety technology necessary.
