What make up oxygen gas?

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 is a very reactive element in its pure state and can make compounds from many other elements.

Where did oxygen get its name?

Discovery date	1774
Discovered by	Joseph Priestley in Wiltshire, England and independently by Carl Wilhelm Scheele in Uppsala, Sweden
Origin of the name	The name comes from the Greek ‘oxy genes’, meaning acid forming.
Allotropes	O2, O3

What is the importance of oxygen in our life short answer?

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.

What is the color of oxygen?

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

How do you explain oxygen to a child?

This element is colorless, odorless, and tasteless. That means even though oxygen is constantly around you, you can’t see it, smell it, or taste it. What is this? Every time you take a breath, you are breathing in oxygen, and you need oxygen to live.

Is air a gas?

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

Is oxygen a noble gas?

Defining the Noble Gases The six noble gases are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). Their atomic numbers are, respectively, 2, 10, 18, 36, 54, and 86. (By contrast, atoms of oxygen—another gas, though not among this group—usually combine to form a molecule, O2.)

Is oxygen a reactive gas?

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 gas or metal?

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 the symbol for oxygen gas?

OOxygen / Symbol

Can oxygen burn?

Oxygen itself does not burn but a fire needs oxygen to start and to keep burning. When more oxygen is in the air, the fire will burn hotter and faster.
