What forms when two identical atoms react?
When two identical atoms react, a chemical bond is formed. Sometimes the bond can be polar, non polar, or ionic.
Diatomic molecules contain two atoms of the same element, such as H2 and O2. However, in nature the two atoms of the same element may not be identical. They may be isotopes, in which the number of neutrons differs between atoms. So a diatomic molecule consisting of two identical atoms would have to contain two atoms of the same isotope, such as two hydrogen-1 atoms or hydrogen-2 atoms. Note: The 2 after the H and…
Two forms of oxygen are found in the stratosphere. Molecular oxygen (O2), which is made up of two atoms of oxygen (O), and ozone (O3) which, as you can see from its chemical formula, is made up of three oxygen atoms. Ozone is formed when intensive ultra-violet radiation from the Sun breaks down O2 into two oxygen atoms. These highly reactive oxygen atoms can then react with more O2 to form O3.
