What are the similarities and differences between oxygen and ozone?

All are elemental and all are composed of the element oxygen.

An oxygen molecule has 16 protons and 16 electrons.

An ozone molecule has 24 protons and 24 electrons.

The number of oxygen protons is 8+8 and the number of electrons (sharing a pair of electrons) is 8+8-2

The number of ozone protons is 8*3 and the number of electrons is 8*3-4

Similarities: 1. They are all composed of aerobic elements;

2. All of them are non-metallic elements;

3. It is gaseous at room temperature.

Differences: 1. An oxygen molecule contains two oxygen atoms, while an ozone molecule has three oxygen atoms;

2. Oxygen is combustible, while ozone is not.

The reason why oxygen and ozone have different chemical properties is that their molecular structures are different. It doesn't matter if the number of electrons in the outermost shell is the same.

Oxygen is O2 and ozone is O3, and the molecular structure is different between the connected oxygen atoms! Covalent electrons! The amount and location of the determined; Generally speaking, the oxygen atoms that make up oxygen and ozone should be the same (8 protons, 8 neutrons), but there are also 18o and 17o (the relative atomic mass of oxygen is an oxygen isotope of 18 (17)), but the number of protons is constant, ozone is made up of 3 oxygen atoms, and oxygen is made up of 2 oxygen atoms.

Oxygen is one of the components of air and is colorless, odorless, and tasteless. Oxygen is denser than air, with a density of grams in the standard condition (0 and atmospheric pressure 101325 Pa), soluble in water, but very little soluble. At a pressure of 101 kPa, oxygen turns into a pale blue liquid at about -180 degrees Celsius and a snowflake-like pale blue solid at about -218 degrees Celsius.

Oxygen is a gas necessary for combustion and respiration of animals and plants, oxygen-rich air is used for medical treatment and high-altitude flight, pure oxygen is used in steelmaking and cutting and welding metals, and liquid oxygen is used as an oxidizer for rocket engines.

Ozone is an allotrope of oxygen, and at room temperature, it is a blue gas with a special odor. Ozone is produced when oxygen in the atmosphere undergoes photochemical reactions, so the ozone layer is formed at a vertical altitude of 15 25 km above the ground, and its concentration is.

1. The number of atoms that make up the molecule is different, oxygen is O2, ozone is O3

2. The resistance of atomic exclusion is different. Ozone has an isosceles triangular structure, where three oxygen atoms are located at the three vertices of the triangle.

Ozone and oxygen, both of which are elemental substances composed of only oxygen atoms, can be said to have the same root and origin, and it is not an exaggeration to call them "siblings". Let's first review the history of the discovery of this pair of "difficult brothers".

1.Oxygen is discovered.

1771 In 1775, the Swede Schoeller, the Englishman Priestley and the Frenchman Lavoisier all discovered the existence of oxygen. However, the first strike is stronger

In 1775, Lavoisier was the first to report his discoveries to the French Academy of Sciences.

In 1777, Lavoisier named the new substance oxygen.

Thus, the discovery of oxygen is attributed to Lavoisier alone, and the discovery of oxygen is undoubtedly the beginning of modern chemical research, so Lavoisier is respected as the "father of chemistry" in modern times.

Ozone was discovered about a decade later, but the "treatment" was vastly different

In 1785, the Germans smelled an unpleasant stench when using the motor, but no one cared about the peculiar smell.

In 1840, the German scientist Schubeye smelled a similar odor when conducting sulfuric acid electrolysis experiments, which was very similar to the smell of spark discharge and lightning in the atmosphere.

The name ozone** is a Greek word for foul smell. It can be seen that ozone has not been taken seriously since its discovery, and it is still disliked because of its smell.
