What is oxygen Short answer?

Oxygen is a colourless, odourless, tasteless gas essential to living organisms, being taken up by animals, which convert it to carbon dioxide; plants, in turn, utilize carbon dioxide as a source of carbon and return the oxygen to the atmosphere.

What is called oxygen?

Oxygen is a chemical element – a substance that contains only one type of atom. Its official chemical symbol is O, and its atomic number is 8, which means that an oxygen atom has eight protons in its nucleus. Oxygen is a gas at room temperature and has no colour, smell or taste. Oxygen is found naturally as a molecule.

What is oxygen and example?

Oxygen is a natural gaseous element with an atomic number of 8 and an atomic weight of 15.96. In the periodic table, it belongs to the chalcogens. It is a reactive nonmetal with an electron configuration of He 2s2 2p4.

What is oxygen made out of?

Under standard conditions oxygen forms a gas that is composed of molecules consisting of two oxygen atoms (O2). This is called a diatomic gas. In this form oxygen is a colorless, odorless, tasteless gas. Oxygen also exists as the allotrope ozone (O3).

What is oxygen Short answer? – Related Questions

Why is oxygen so important?

Most living things need oxygen to survive. Oxygen helps organisms grow, reproduce, and turn food into energy. Humans get the oxygen they need by breathing through their nose and mouth into their lungs. Oxygen gives our cells the ability to break down food in order to get the energy we need to survive.

Why is it called oxygen?

The name comes from the Greek ‘oxy genes’, meaning acid forming. A vertical column in the periodic table.

What is the main source of oxygen?

At least half of Earth’s oxygen comes from the ocean.

The majority of this production is from oceanic plankton — drifting plants, algae, and some bacteria that can photosynthesize. One particular species, Prochlorococcus, is the smallest photosynthetic organism on Earth.

How is oxygen created?

The answer is tiny organisms known as cyanobacteria, or blue-green algae. These microbes conduct photosynthesis: using sunshine, water and carbon dioxide to produce carbohydrates and, yes, oxygen.

Where is oxygen naturally found?

Oxygen occurs mainly as an element in the atmosphere. It makes up 20.948 percent of the atmosphere. It also occurs in oceans, lakes, rivers, and ice caps in the form of water. Nearly 89 percent of the weight of water is oxygen.

What is pure oxygen?

Pure oxygen is a term used to describe a gaseous mixture containing more than 90 percent oxygen. Regular air we breathe contains roughly 21 percent oxygen.

Can you breathe 100% oxygen?

The concentration of oxygen in normal air is only 21%. The high concentration of oxygen can help to provide enough oxygen for all of the organs in the body. Unfortunately, breathing 100% oxygen for long periods of time can cause changes in the lungs, which are potentially harmful.

Can humans breathe pure oxygen?

To breathe pure oxygen at that level for any longer can have toxic results, including “shock lung,” or adult respiratory distress syndrome. In infants, too much pure oxygen for too long a time can also lead to retinal problems as the blood vessels in their eyes won’t develop properly.

Who discovered oxygen?


How does the body use oxygen?

Your body cells use the oxygen you breathe to get energy from the food you eat. This process is called cellular respiration. During cellular respiration the cell uses oxygen to break down sugar. Breaking down sugar produces the energy your body needs.

Can you see oxygen?

Scientists at Research Centre Jülich have made individual oxygen atoms directly visible with an electron microscope in a certain class of materials, the perovskites.

What are the properties of oxygen?

Key Properties
  • It is a colorless, odorless and tasteless gas.
  • It readily dissolves in cold water.
  • It is highly reactive and form oxides with almost all elements except noble gases.
  • Liquid oxygen is strongly paramagnetic.
  • It exists in three allotropic forms- monoatomic, diatomic and triatomic.
  • It supports combustion.

What Colour is oxygen?

The gas is colorless, odorless, and tasteless. The liquid and solid forms are a pale blue color and are strongly paramagnetic.

What are 5 characteristics of oxygen?

Oxygen O₂ is a gas without color, taste or smell. It dissolves poorly in water, and boils at a temperature of -183 degrees Celsius. Oxygen in liquid form is light blue in color, and in solid form the element forms dark blue crystals. Oxygen melts at a temperature of -218.7 degrees Celsius.

What is the value of oxygen?

Humans along with other mammals require oxygen necessarily. They need it to carry out their daily tasks and smooth functioning of the body. Even the cells in our body need oxygen to function properly. All the living beings inhale oxygen in their lungs for proper respiration.

Is air a oxygen?

Air is mostly gas

The air in Earth’s atmosphere is made up of approximately 78 percent nitrogen and 21 percent oxygen. Air also has small amounts of other gases, too, such as carbon dioxide, neon, and hydrogen.

Is oxygen a metal?

Oxygen is a non-metal, and it is one of the most abundant non-metal found in the Earth’s crust.
