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 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
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 helium?
Helium has many unique properties: low boiling point, low density, low solubility, high thermal conductivity and inertness, so it is use for any application which can explioit these properties. Helium was the first gas used for filling balloons and dirigibles.
What is the chemical formula for oxygen?
Oxygen is written as O2 when there are two oxygen atoms in the molecule. Pure oxygen doesn’t generally exist as individual atoms, two oxygen atoms bond together to form an oxygen molecule.
How do we use oxygen in our everyday lives?
Everyday Uses of Oxygen
Respiration: • Every living creature and plant requires oxygen to survive.
Metallurgy: • The production of steel is reliant upon oxygen where it is used in a blast furnace to turn carbon into carbon dioxide, which reduces the iron oxides to pure iron.
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 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).
What are the physical and chemical properties of sulfur?

What are the physical and chemical properties of nitrogen?
Characteristics. Nitrogen gas (chemical symbol N) is generally inert, nonmetallic, colorless, odorless and tasteless. Its atomic number is 7, and it has an atomic weight of 14.0067. Nitrogen has a density of 1.251 grams/liter at 0 C and a specific gravity of 0.96737, making it slightly lighter than air.
Is oxygen flammable gas?
After nitrogen, the most abundant gas in our air is oxygen. Here’s where it gets complicated: Oxygen is also not flammable, but it is a high-energy gas that very readily oxidizes other materials. For something to burn, the reaction requires a fuel (the thing that burns) and an oxidizer like oxygen.
What are the chemical properties of nitrogen gas?
Chemical properties of nitrogen – Health effects of nitrogen – Environmental effects of nitrogenAtomic number7Electronegativity according to Pauling3.0Density1.25*10-3 g.cm-3 at 20°CMelting point-210 °CBoiling point-195.8 °C
What is the use of oxygen?
It is also used to make epoxyethane (ethylene oxide), used as antifreeze and to make polyester, and chloroethene, the precursor to PVC. Oxygen gas is used for oxy-acetylene welding and cutting of metals. A growing use is in the treatment of sewage and of effluent from industry.
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 oxygen and why is it important?
Oxygen is a very important element because we need it to live. It is a part of the air people breathe and the water people drink. Many living things (including humans) need oxygen to live and breathe, though it is poisonous to some forms of life. In liquid state of matter, oxygen is light blue.
Is oxygen a nonmetal metal or metalloid?
The elements with the distinguished honor of being called a metalloid are boron (B), silicon (Si), germanium (Ge), arsenic (As), antimony (Sb), tellurium (Te), and polonium (Po). These elements have some properties that make them metal-like and other properties that make them non-metal-like. It’s a metalloid.
Why is Oxygen is an element?
Oxygen is considered an element because it cannot be broken down any farther.Elements are pure substances that form a single atom.Elements are the simplest building blocks you can break matter down into using purely chemical methods.Oxygen can be found on the periodic table with the atomic number eight.
What are the properties and uses of phosphorus?
These allotropes all have different physical and chemical properties. White phosphorus is a waxy, transparent solid. Its melting point is 44.1°C (111°F) and its boiling point is 280°C (536°F). It has a density of 1.88 grams per cubic centimeter.
Is Oxygen is an 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.
What are the properties of carbon dioxide?
Carbon dioxide is colorless. At low concentrations the gas is odorless however, at sufficiently-high concentrations, it has a sharp, acidic odor. At standard temperature and pressure, the density of carbon dioxide is around 1.98 kg/m3, about 1.67 times that of air.
What are some interesting facts about oxygen?
Oxygen (O) has an atomic number of eight. This odorless, colorless gas has eight protons in the nucleus, and is pale blue in its liquid and solid states. Interesting Oxygen Facts: One fifth of the Earth’s atmosphere is made up of oxygen and is the third most abundant element in the universe by mass.
