WebJan 10, 2024 · 1. O is a singular oxygen atom. O 2 is a molecule made of two oxygen molecules. Our atmosphere is made of mostly O 2, which our bodies have evolved to breathe. We breathe in O 2 and cellular respiration requires it (C 6 H 12 O 6 +6O 2 →6CO 2 +6H 2 O). O is oxygen, while O 2 is dioxygen. WebOccurrence. Oxygen is the most abundant element in the Earth's crust, estimated to comprise 46.7% of it. Oxygen comprises about 87% of the oceans (as H 2 O, water) and 20% of the atmosphere of Earth (as O 2, molecular oxygen, or O 3, ozone).Oxygen compounds, particularly metal oxides, silicates (SiO 4 4-) and carbonates (CO 3 2-), are …
Oxygen is the chemical element with the symbol O and atomic number 8. It is a member of the chalcogen group in the periodic table, a highly reactive nonmetal, and an oxidizing agent that readily forms oxides with most elements as well as with other compounds. Oxygen is Earth's most abundant element, and after hydrogen and helium, it is the third-most abundant element in the universe. At s… WebNov 26, 2024 · Atomic mass of Oxygen is 15.9994 u. Note that each element may contain more isotopes. Therefore this resulting atomic mass is calculated from naturally-occurring isotopes and their abundance. The unit of measure for mass is the atomic mass unit (amu). One atomic mass unit is equal to 1.66 x 10 -24 grams.

WebJul 30, 2008 · Carbon has 6 protons, so its atomic number is 6; oxygen has 8 protons, so its atomic number is 8. Uranium has 92 protons, so its atomic number is 92! If we count the number of protons plus neutrons, we get an atom's atomic mass. Most elements come in different versions, called "isotopes", with different numbers of neutrons.
