What are the characteristics of oxygen?

Ozone (O3) is toxic and if inhaled can damage the lungs. Characteristics: Oxygen in its common form (O2) is a colorless, odorless and tasteless diatomic gas. Oxygen is extremely reactive and forms oxides with nearly all other elements except noble gases.

What are the physical properties of the oxygen family?

NonmetalChalcogenPeriod 2 element

What are the chemical and physical properties of oxygen gas?

Oxygen exists in three allotropic forms. Allotropes are forms of an element with different physical and chemical properties. The three allotropes of oxygen are normal oxygen, or diatomic oxygen, or dioxygen; nascent, atomic, or monatomic oxygen; and ozone, or triatomic oxygen.

What does oxygen do?

Why do we breathe? (We breathe because oxygen is needed to burn the fuel [sugars and fatty acids] in our cells to produce energy.) What happens in the process of respiration? (Oxygen is brought into the lungs via breathing, where it is transported by red blood cells to the entire body to be used to produce energy.

What is the use of oxygen in the human body?

One critical role that oxygen plays in the body is that it is used to oxidize our food, in the process of cellular respiration, thus releasing energy, which is eventually stored in ATP in the electron transport chain in mitochondria, and in glycolysis in the cytoplasm.

Is Solid oxygen possible?

Solid oxygen. Solid oxygen forms at normal atmospheric pressure at a temperature below 54.36 K (−218.79 °C, −361.82 °F). Solid oxygen O2, like liquid oxygen, is a clear substance with a light sky-blue color caused by absorption in the red part of the visible light spectrum.

Is Oxygen is a element?

Element No. 8 on the Periodic Table of the Elements is a colorless gas that makes up 21 percent of Earth’s atmosphere. Because it’s all around, oxygen is easy to dismiss as dull and inert; in fact, it’s the most reactive of the non-metallic elements.

Is oxygen a solid or a liquid?

Could be the 3 of them, just depends on the temperature and pressure. Of course on earth, with our usual temperature and pressure, we know Oxygen as a gas, but it can exist as a liquid and as a solid.

How oxygen is produced?

Oxygen can be produced from a number of materials, using several different methods. The most common natural method is photo-synthesis, in which plants use sunlight convert carbon dioxide in the air into oxygen. This offsets the respiration process, in which animals convert oxygen in the air back into carbon dioxide.

What are the physical properties of oxygen?

How many protons neutrons and electrons are in oxygen?

The number eight also means that oxygen has eight protons in the nucleus. The number of protons and the number of electrons are always the same in an element that is neutral and has no charge. Therefore oxygen has 8 electrons. You will find that the atomic weight of oxygen is about 16.

What is the state of oxygen?

Data ZoneClassification:Oxygen is a chalcogen and a nonmetalColor:colorlessAtomic weight:15.9994State:gasMelting point:-218.3 oC, 54.8 K

What is the family of oxygen?

The oxygen family, also called the chalcogens, consists of the elements found in Group 16 of the periodic table and is considered among the main group elements. It consists of the elements oxygen, sulfur, selenium, tellurium and polonium. These can be found in nature in both free and combined states.

What are the chemical and physical properties of oxygen gas?

Oxygen exists in three allotropic forms. Allotropes are forms of an element with different physical and chemical properties. The three allotropes of oxygen are normal oxygen, or diatomic oxygen, or dioxygen; nascent, atomic, or monatomic oxygen; and ozone, or triatomic oxygen.

Is oxygen malleable?

Physical Properties of nonmetals: Physical State: Most of the non-metals exist in two of the three states of matter at room temperature: gases (oxygen) and solids (carbon). Non-Malleable and Ductile: Non-metals are very brittle, and cannot be rolled into wires or pounded into sheets.

Why is oxygen named Oxygen?

Priestley called the gas produced in his experiments ‘dephlogisticated air’ and Scheele called his ‘fire air’. The name oxygen was created by Antoine Lavoisier who incorrectly believed that oxygen was necessary to form all acids. Oxygen is a highly reactive element and is capable of combining with most other elements.

What are the properties of fluorine?

What is the use of oxygen?

Photosynthesis uses energy from the sun to split water into oxygen and hydrogen. The oxygen passes into the atmosphere and the hydrogen joins with carbon dioxide to produce biomass. When living things need energy they take in oxygen for respiration. The oxygen returns to the atmosphere in the form of carbon dioxide.

How does oxygen react with other elements?

Oxygen is very reactive with Alkali metals. Alkali metals are given the name alkali because the oxides of these metals react with water to form a metal hydroxide that is basic or alkaline. Lithium produces an oxide, sodium produces a peroxide, and potassium, cesium, and rubidium produce superoxides.

Is oxygen brittle?

Non-metallic elements are very brittle, and cannot be rolled into wires or pounded into sheets. Non-metallic elements exist, at room temperature, in two of the three states of matter : gases (such as oxygen) and solids (such as carbon).

Is oxygen a luster?

The non-metals exist in two of the three states of matter at room temperature: gases (such as oxygen) and solids (such as carbon). The non-metals have no metallic luster, and do not reflect light. They have oxidation numbers of ±4, -3, and -2. Oxygen.

How did Joseph discover oxygen?

Joseph Priestley: The man who discovered Oxygen. One of the founding fathers of chemistry, Joseph Priestley (1733-1804) stumbled across photosynthesis, is credited with the discovery of oxygen and accidentally brought us soda water. It is for this discovery that he is best remembered today.

What is the air made up of?

The air you breathe is made up of lots of other things besides oxygen! Oxygen only makes up about 21% of air. About 78% of the air you breathe is made up of another gas called nitrogen. There are also tiny amounts of other gases like argon, carbon dioxide and methane.
