What does the element O2 represent?
O2 refers to oxygen gas, or oxygen in its diatomic form. This is because oxygen atoms aren’t completely stable on their own and need to bond in order to exist on its own.
Why is the atomic number of oxygen 8?
The atomic number of oxygen is 8, because oxygen has eight protons in the nucleus.
Does the atomic number represent electrons?
The atomic number uniquely identifies a chemical element. It is identical to the charge number of the nucleus. In an uncharged atom, the atomic number is also equal to the number of electrons.
Why is oxygen O2 and not just O?
Oxygen is available as O2 not as O because pure oxygen is highly reactive it will combine with anything to form oxides,disconnected atoms have a very strong tendency to form bonds. So if there is nothing else available for oxygen atom to combine it will combine with another oxygen atom to form an oxygen molecule.

Oxygen/Atomic mass
The most common Isotope is found by rounding the Weighted average found on the periodic table to the nearest whole number. In this case Oxygen has a Weighted Average Atomic Mass of 15.999 AMU. So the Mass Number is 16.
What does the atomic number of an element represent what does the mass number of an atom represent?
– Remember that the atomic number – is the number of PROTONS in the nucleus of the atom of that element. – Remember that the mass number (a.k.a atomic mass)- is the number of PROTONS and NEUTRONS in the nucleus of the atoms of that element.
Can humans breathe O1?
Originally Answered: Can we breath with O1 or O3 instead of O2? No. The oxygen radical (O•) is highly toxic to all forms of life. It is nonetheless produced in tiny quantities in living cells, but we have special enzymes for dealing with it.
