The ozone gas is a pale blue colour gas with a sharp odour. It is more soluble in non-polar solvents and less soluble in water. Moreover, two oxygen atoms in the ozone bind together with a double bond, and there is a dative bond between one oxygen atom with another oxygen atom.
However, it shows resonance stabilization; thus, the actual structure of this molecule is a hybrid structure. There, the O-O bond length is similar between three atoms. The central oxygen atom has sp 2 hybridization with one lone pair.
Moreover, the ozone has bent geometry. Also, it is a polar molecule. And, since it is a strong oxidizing agent, ozone is highly reactive. Besides, this gas forms from the oxygen when there is sunlight. Oxygen is a chemical element with the atomic number 8 and symbol O and ozone is a gaseous compound with chemical formula O 3. Generally, when we say oxygen, we refer to the oxygen gas. Hence, the key difference between oxygen and ozone is that the oxygen gas is a diatomic gaseous molecule of oxygen element, whereas the ozone is a triatomic gaseous molecule of oxygen.
Moreover, there is a difference between oxygen and ozone in their colors as well. That is; the oxygen is a colourless gas, but ozone is a pale blue gas. Furthermore, another significant difference between oxygen and ozone is that the ozone gas can be harmful at lower atmospheric levels but, oxygen is not a harmful gas.
Besides, in the atmosphere, oxygen gas occurs in much higher quantities than ozone. Apart from that, ozone is less stable than oxygen. Therefore, the oxidation ability of ozone is higher than that of oxygen. Thus, allotropes are different structural modifications of an element.
Both diatomic ozone O 2 and triatomic ozone O 3 are made up of oxygen atoms but they have different chemical and physical properties. While animals need oxygen to breathe, ground-level ozone is an air pollutant with harmful effects on the respiratory systems of animals. The ozone layer in the upper atmosphere filters potentially damaging ultraviolet light from reaching the Earth's surface.
Ozone is present in low concentrations throughout the Earth's atmosphere. There is a layer of ozone in the upper atmosphere. Oxygen, on the other hand, is mostly found in the lower layers of the atmosphere.

Although some stratospheric ozone is transported into the troposphere, and some VOC and NOx occur naturally, the majority of ground-level ozone is the result of reactions of man-made VOC and NOx. Significant sources of VOC are chemical plants, gasoline pumps, oil-based paints, autobody shops, and print shops.
Nitrogen oxides result primarily from high temperature combustion. Significant sources are power plants, industrial furnaces and boilers, and motor vehicles. Many people mistakenly believe that tropospheric ozone concentrations are high only in major urban areas, but high ambient ozone concentrations can and do occur anywhere.
It is also formed in smaller cities like Raleigh, NC and Cincinnati, OH, and it is transported hundreds of miles downwind from where it is created to affect ambient air quality in other urban and rural areas.
Where ozone is formed, peak concentrations usually occur during afternoon hours, when sunlight is the most intense. However, areas downwind of major sources of VOC and NOx may experience ozone peaks in the afternoon and evening, after wind has carried ozone and its VOC and NOx precursors many miles from their sources.
Thus, high ozone concentrations can occur in remote areas and at various times of day, including during the early evening or night. Figure 1: U. This map depicts ozone concentrations by U.
