Explanation:

The given diagram shows an [tex]O_{2}[/tex] molecule. As atomic number of oxygen is 8 so, its electronic distribution is 2, 6. Also, atomic mass of an oxygen atom is 16.

This means it contains 8 protons and 8 neutrons.

When n = 1 orbit then it means the number of electrons present in very first orbit of an atom.

When there will be sharing of electrons between the two chemically combining atoms then there will be formation of a covalent bond.

Therefore, according to the diagram:

  • There are 2 electrons in the n = 1 orbit of each atom.
  • Each atom has 6 electrons in its n = 2 orbit.
  • Each atom has 8 protons in its nucleus.
  • Each atom has 8 total electrons.
  • There are 6 electrons in oxygen's outer shell before sharing electrons.
  • There are 2 electrons being shared between the two atoms.
  • Covalent bonds exist between the two oxygen atoms.
