Given a formula for oxygen: what is the total number of electrons shared between the atoms represented in this formula

Answer is: the total number of electrons shared between the atoms is four.

Molecule of oxygen is nonpolar because double linear bonds (O=O).

Oxygen (O) is an element with atomic number 8, it means it has eight protons and eight electrons, so atom has neutral charge. Oxygen is a nonmetal.

Electron configuration of oxygen atom: ₈O 1s² 2s² 2p⁴.

Oxygen atom has six valence electrons, so it is in 16 group of Periodic table of elements.

Two valence electrons from both oxygen atoms form double bond (O::O) at oxygen molecule.

it is important to conserve water because there is very limited amount of freshwater here on earth and if we are not smart about how we use it we will only be runnning out of our supply faster than neccessarry.
