what is oxygen

​

Answer 1

Answer:

Oxygen (O), nonmetallic chemical element of Group 16 (VIa, or the oxygen group) of the periodic table. 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. Oxygen forms compounds by reaction with practically any other element, as well as by reactions that displace elements from their combinations with each other; in many cases, these processes are accompanied by the evolution of heat and light and in such cases are called combustions. Its most important compound is water.

Answer 2

• Oxygen is a non-metal element that is a gas at room temperature. Its molecules contain two oxygen atoms.

• Oxygen is vital for respiration, which is the process that transfers energy from glucose to cells.

• Oxygen is necessary for burning to occur. However, burning will only happen when the mixture of fuel and oxygen is hot enough.
