The Aurora Borealis (Northern Lights) and the Aurora Australis (Southern Lights).
All elements can exist as individual atoms in excited states. However, at standard temperature and pressure, hydrogen, nitrogen, oxygen, fluorine, chlorine, bromine, and iodine exists as diatomic molecules.
Atoms are important because they form the basic building blocks of all visible matter in the universe.
When two or more atoms combine together the form a molecule. One example of this relationship is H2O (water), which is a combination of 2 atoms of hydrogen (1 molecule of hydrogen) and 1 atom of oxygen.
They do, if excited.
No. Molecules are made of atoms.
The heat energy of a substance is determined by how active its atoms and molecules are. A hot object is one whose atoms and molecules are excited and show rapid movement. A cooler object's molecules and atoms will be less excited and show less movement. When these guys are in the excited state, they take up a lot of space because they're moving around so fast. When the atoms and molecules settle down, or cool down, they take up less space...

in the visible light range
You would expect to find nitrogen and oxygen as molecules in the atmosphere, and argon as individual atoms.
Exosphere
No. Atoms and molecules are far smaller than the wavelengths of visible light, so light cannot be used to image them.
The CFC's molecules are ODS. They react with ozone to deplete it. The Chlorine and Fluorine are main atoms.
Steam and Ice are made up of Water Molecules which are made up of two hydrogen atoms and one oxygen atom. Steam is water turned to gas by having its molecules excited by heat. Ice is water where the molecules have slowed down because of cold temperatures, forming a solid. Hope this helps.

The ionosphere can be described as the upper atmosphere of the planet Earth. It is made up of electrons, atoms, and molecules.
Atoms are important because they form the basic building blocks of all visible matter in the universe.
Atoms have protons, neutrons and electrons that are not visible with naked eyes. Infact, even atoms are too small to be seen with naked eyes.
