O is the chemical symbol but as oxygen readily combines into molecules it usually exists as O2 or as O3 (ozone)
On a Periodic Table it is O but it can also be 02
p.s. whoever is supervising this post isnt doing a good job because before i changed this answer it was very rude, nasty and unhelpful
Oxygen = O2
oxygen
There are 3 oxygens so it should be trioxide and not dioxide.
Sodium sulphite is the IUPAC name. Its formula is Na2SO3 (NB there are only 3 oxygens in sulfite.

Liquid density at boiling point (90 K) is 1.141 g·cm−3
Oxygen is in the second period.
non-metal
This name is chalcogens.
It tells you that is is composed of silicon (Si) and oxygen (O), in a ratio of 2 oxygens for each silicon.
The chemical name for the formula P2O5 is phosphorous pentoxide. It has a relatively complex structure of two rings. Each ring has multiple phosphorus atoms double bonded to oxygens.
The chemical makeup of glucose is C6H12O6.
The name origin of oxygen is the Greek words oxus(acid) and gennan (generate.)
PO43-.This in superscript form, hence, the formula is one phosphorous, 4 oxygens, and 3- valence electrons.
There are 3 oxygens so it should be trioxide and not dioxide.
Carbon dioxide, CO2

it has no oder .
