The atom is a complex system of particles ... With eight protons and eight neutrons, oxygen-16 has an extremely stable ...

When building an atom, pay close attention to the particles' electrical charges. Protons have a charge of +1. Electrons have a charge of -1. Neutrons are neutral, as its name implies. A stable ...

Oxygen was the first stable isotope used to determine migratory history in marine environments. Stable isotope analyses using marine oxygen have used barnacle shells attached to the study animal.

When two hydrogen atoms and an oxygen atom get close enough, the electron from each atom feels an attraction from the protons in the other atom's nucleus. This attraction pulls the atoms together. The ...
