What type of substance is 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.

What type of mixture is air?

homogeneous mixture

Air is an example of a solution as well: a homogeneous mixture of gaseous nitrogen solvent in which oxygen and smaller amounts of other gaseous solutes are dissolved.

Is air a molecule or atom?

The air in our atmosphere is composed of molecules of different gases. The most common gases are nitrogen (78%) oxygen (about 21%) and argon (almost 1%). Other molecules are present in the atmosphere as well but in very small quantities.

Are there atoms in everything?

(Matter is anything that can be touched physically.) Everything in the universe (except energy) is made of matter and so everything in the universe is made of atoms. An atom itself is made up of three tiny kinds of particles called subatomic particles: protons neutrons and electrons.

Is air made of matter?

Air is our most familiar example of the state of matter we call gas. … But like solids and liquids air is matter. It has weight (more than we might imagine) it takes up space and it is composed of particles too small and too spread apart to see.

  • Oxygen — 21 percent.
  • Argon — 0.93 percent.
  • Carbon dioxide — 0.04 percent.
  • Trace amounts of neon helium methane krypton and hydrogen as well as water vapor.

Is air a compound?

Air is a mixture but not compound. Its constituents can be separated. For example: oxygen nitrogen etc. … Air shows properties same as the constituent gases present in it.

Is air a pure substance?

A substance that has a fixed chemical composition throughout is called a pure substance such as water air and nitrogen. A pure substance does not have to be of a single element or compound.

Are all gases in air elements?

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 the air that we breathe an element compound mixture or pure substance?

We breathe (mostly) an homogeneous mixture of elements: elemental nitrogen N2 elemental oxygen O2 . The mixture is homogeneous because the dioxygen and dinitrogen are in the same phase and state.

What are oxygen molecules made of?

Oxygen is a non-metal element and is found naturally as a molecule. Each molecule is made up of two oxygen atoms that are strongly joined together. Oxygen has low melting and boiling points so it is in a gas state at room temperature.

What gases do we inhale and exhale?

In other words: we inhale high concentrations of oxygen which then diffuses from the lungs into the blood while high concentrations of carbon dioxide diffuses from the blood into the lungs and we exhale.
