Ozone forms readily in the stratosphere as incoming ultraviolet radiation breaks molecular oxygen (two atoms) into atomic oxygen (a single atom). In that process, oxygen absorbs much of the ultraviolet radiation and prevents it from reaching the Earthâs surface where we live.
The Reaction between Magnesium and Oxygen. Magnesium is in group 2 of the periodic table. A magnesium atom will lose 2 electrons to form a stable 2+ ion. Oxygen is in group 6 of the periodic table.An oxygen atom will gain 2 electrons to form a stable 2- ion. In this example the electrons are shown as dots and crosses.agnesium is in group 2 of the periodic table. A magnesium atom will lose 2 electrons to form a stable 2+ ion.
