it's because it starts with the letter "O" and its easier 2 remember when u do Equations
The formula for Oxygen is actualy "O" but because one oxygen atom is never alone it is written as O₂
Oxygen is written as "O" when it is represented as an element in the periodic table.
O2 Although O is the symbol for oxygen, it occurs naturally as a diatomic molecule and is therefore normally written O2.
It is written correctly in the question. The symbol is O.
Ca = calcium , O = oxygen and written together like CaO it stands for calcium oxide.
The chemical symbol for oxygen is O, but it is frequently written as O2. This is because when oxygen is not chemically combined with anything else, it bonds to another oxygen atom, making an oxygen molecule. Oxygen is a diatomic molecule, and that's how we encounter it in air.
Anna E. O. Fisher has written: 'Novel agents for the detection and suppression of reactive oxygen and nitrogen species'
The symbol o written above a reaction arrow indicates that the reaction is carried out under an oxygen atmosphere.
The nuclear formula for oxygen is represented as ( \text{O} ) with a mass number of 16, written as ( ^{16}\text{O} ). This indicates that oxygen has 8 protons and 8 neutrons in its nucleus. The atomic number of oxygen is 8, which corresponds to the number of protons.
The symbol for oxygen is O.
O is the the symbol of the element oxygen.
oxygen is pronounced likeox as in oxenEjun
