What is O2 mean?
Also what is oxygen gas the formula?
Please could someone answer this?
O2 is the chemical formula for oxygen gas. Oxygen (O) is an element on the periodic table, and it exists as a diatomic molecule, meaning it naturally pairs with another oxygen atom to form O2.
To determine the chemical formula for oxygen gas, you can refer to the periodic table, which provides information about the elements. The symbol for oxygen is "O," and by observing its position on the periodic table, you can find that oxygen has an atomic number of 8. This indicates that it has 8 protons in its nucleus. Since oxygen typically exists as O2, this means two oxygen atoms, each with 8 protons and a total of 16 protons, form one molecule of oxygen gas.
In summary, O2 is the chemical formula for oxygen gas, which consists of two oxygen atoms bonded together.
