What You'll Learn
Oxygen is a non-metal
The modern concept of the element of oxygen developed over five centuries and included many related discoveries and unsuccessful theories. It is commonly believed that the element was discovered independently by Carl Wilhelm Scheele in 1773 or earlier and Joseph Priestley in 1774. However, Priestley called oxygen "dephlogisticated air" and did not recognize it as a chemical element. It was Antoine Lavoisier who first recognized oxygen as a chemical element and correctly characterized its role in combustion.
The non-metal oxygen is a poor conductor of electricity. This is because non-metals are not dense enough and do not have sufficient free electrons to pass electricity efficiently. In non-metals, electrons are held tightly and are not allowed to move freely. On the other hand, metals conduct electricity because of the presence of free-moving electrons, which offer less resistance to the flow of current.
Oxygen has many industrial uses, including the production of steel, plastics, and textiles, as well as welding and cutting of metals. It is also used in rocket propellant, oxygen therapy, and life support systems in aircraft, submarines, spaceflight, and diving.

Insufficient free electrons
Oxygen is a non-metal and a poor conductor of electricity. This is due to the insufficient number of free electrons in the element. Electrons are the negatively charged particles that orbit the nucleus of an atom. In metals, these electrons are free to move, which is why they conduct electricity efficiently. The force that makes the current flow through the conductor is known as voltage.
In non-metallic elements like oxygen, the electrons are not as free to move. They are held tightly and are not allowed to move freely. This is because non-metals are not dense enough to pass electricity efficiently. The best conductors of electricity are typically metals, such as silver and copper.
The property that allows a substance to conduct electricity is called conductivity. Conductivity is dependent on the number of free electrons in the substance. Metals have high conductivity due to their high number of free electrons. On the other hand, non-metals like oxygen have low conductivity due to their low number of free electrons.
The electrons in oxygen are tightly bound and are not easily released. This is why oxygen does not have sufficient free electrons to pass electricity efficiently. It is important to note that while oxygen is a poor conductor of electricity, it is still an excellent supporter of combustion. This means that while oxygen does not conduct electricity on its own, it plays a crucial role in the combustion process, which is essential for various applications, including energy production and industrial processes.

Electrons are held tightly
Oxygen is a non-metal and a poor conductor of electricity. This is because the electrons in non-metals are held tightly and are not allowed to move freely. Metals, on the other hand, have electrons that are free to move, allowing them to conduct electricity efficiently. The best conductors of electricity are silver and copper.
In the case of non-metals like oxygen, the electrons are strongly attracted to the nucleus, which prevents them from moving around the material and carrying a current. This is in contrast to metals, where the attraction of the nucleus on the valence electrons is minimal, allowing these electrons to move freely and conduct electricity.
The ability of a substance to conduct electricity depends on the availability of free electrons that can move within the material. In metals, there is a high density of free electrons due to the weak attraction of the nucleus. This high electron mobility results in low resistance to the flow of electric current. Conversely, non-metals like oxygen have a low density of free electrons due to the strong attraction of the nucleus, leading to high resistance and poor conductivity.
The tight binding of electrons in oxygen restricts their movement and hinders the flow of electric current. This characteristic of oxygen, along with its non-metallic nature, contributes to its poor conductivity. While oxygen may have some limited ability to conduct electricity under certain conditions, it is generally considered a poor conductor in comparison to metals and other materials with higher electron mobility.
In summary, the poor conductivity of oxygen can be attributed to the fact that its electrons are held tightly, preventing their free movement and impeding the flow of electric current. This understanding highlights the fundamental difference between metallic and non-metallic conductors and provides insight into the electrical behaviour of various substances.

Poor conductor of heat
Oxygen is a non-metal and a poor conductor of electricity. Conductivity is the property that allows materials to conduct electricity. Electric current is the flow of electrons in a conductor, and the force required to make the current flow through the conductor is known as voltage. Metals conduct electricity because they have electrons that are free to move, which means they offer less resistance to the flow of current. In contrast, non-metals like oxygen do not have sufficient free electrons to pass electricity efficiently. In non-metals, electrons are held tightly and are not allowed to move freely, so they are poor conductors of electricity.
Oxygen is also a poor conductor of heat. This means that it does not transfer thermal energy well. Metals, on the other hand, are typically good conductors of both heat and electricity due to their high electron mobility.
The poor conductivity of oxygen is related to its atomic structure and the strength of its atomic bonds. In metals, the attraction of the nucleus on the valence electrons is minimal, allowing these electrons to move freely and conduct electricity efficiently. In contrast, non-metals like oxygen have stronger attractions between their nuclei and valence electrons, resulting in reduced electron mobility and poorer conductivity.
The ability of a substance to conduct electricity is also influenced by its density. Metals are generally denser than non-metals, contributing to their higher conductivity. However, oxygen is an exception among non-metals as it is denser than air, yet it still exhibits poor conductivity due to the tight binding of its electrons.
In summary, oxygen's status as a non-metal, with its tightly bound electrons and relatively high density, makes it a poor conductor of both heat and electricity.

Supports combustion
Oxygen is a neutral gas that supports combustion. It is the main component of air that supports combustion. Without oxygen, combustion cannot take place.
Oxygen is a supporter of combustion and is used up in burning. It is a chemical element that reacts with various simple substances, forming oxides as a result of the interaction. This interaction with chemical elements is called the oxidation reaction. For example, when hydrogen burns in the presence of oxygen, it oxidizes to water.
Pure oxygen has unique properties that oxygen in the air does not possess. Air contains five times less oxygen than pure oxygen of the same volume. The air is mixed with a large amount of nitrogen, which does not burn itself and does not support combustion. Therefore, if the oxygen in the air around a flame is already expended, the next portion of oxygen must get through nitrogen and the products of combustion.
The more oxygen supplied to the burning substance per unit of time, the brighter the flame, the higher the temperature, and the more intense the combustion process.
