What do the following abbreviations stand for in O2? ›

iii) O₂ denotes a molecule of oxygen gas.

O2 represents an oxygen molecule with 2 atoms. So 2 in this formula represents the number of atoms in the formation of that molecule.

O₂ represents the oxygen molecules.

O denotes atom of oxygen. O₂ denotes a molecule of oxygen gas. 3O₂ denotes three molecules of oxygen gas.

2O represents two oxygen atmos. 3. O2 stands fir oxygen molecule that is present in atmosphere. 4. 3O2 stands for three oxygen molecule.

Solution. O stands for an atom of oxygen. 2O refers to two atoms of oxygen which are not chemically bonded. O₂ refers to a molecule of oxygen in which atoms are chemically bonded to give a molecule of oxygen gas. 3O₂ refers to three molecules of oxygen.

Ozone (O3) is a highly reactive gas composed of three oxygen atoms. It is both a natural and a man-made product that occurs in the Earth's upper atmosphere. (the stratosphere) and lower atmosphere (the troposphere). Depending on where it is in the atmosphere, ozone affects life on Earth in either good or bad ways.

In the above reaction oxygen is written as O2 because it is diatomic.

i a 2O = 2 atoms of oxygen b O2 = Diatomic oxygen c O3 = Triatomic oxygen / ozone d H2O=Two atoms of hydrogen and one atom of oxygen construct one molecule of water H2O ii Potassium carbonate - K2CO3 Calcium chloride - CaCl2 iii Formula unit mass of any compound is the sum of atomic masses of all atoms in the formula ...

How is O2 written? ›

Oxygen is written as O2 when there are two oxygen atoms in the molecule. Pure oxygen doesn't generally exist as individual atoms, two oxygen atoms bond together to form an oxygen molecule. This is because oxygen is highly reactive, disconnected atoms have a very strong tendency to form bonds.

Oxygen is a chemical element with an atomic number of 8 (it has eight protons in its nucleus). Oxygen forms a molecule (O₂) of two atoms which is a colorless gas at normal temperatures and pressures.

See O is the symbol of oxygen and O2 is the chemical equation for oxygen ,it says that OXYGEN has TWO ATOMS IN ONE MOLECULE.
