Which elements will occur as diatomic molecules and cannot exist as individual atoms?
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.
Why is the study of atoms and molecules important?
Atoms are important because they form the basic building blocks of all visible matter in the universe.
What don't atoms radiate?
They do, if excited.
How are atoms and molecules related and give an example?
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.
Are atoms bigger than molecules?
No. Molecules are made of atoms.
What is heat energey?
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...

The bright-line spectrum produced by the excited atoms of an element contains wavelengths that are?
in the visible light range
Which of the gases in the earth's atmosphere would you expect to find as molecules and which as individual atoms?
You would expect to find nitrogen and oxygen as molecules in the atmosphere, and argon as individual atoms.
Which layer of the atmosphere loses atoms and molecules due to weak gravity?
Exosphere
Could a laser light with holograph see molecules and atoms?
No. Atoms and molecules are far smaller than the wavelengths of visible light, so light cannot be used to image them.
What atoms in the CFC molecule can destroy thousands of ozone molecules in the upper atmosphere?
The CFC's molecules are ODS. They react with ozone to deplete it. The Chlorine and Fluorine are main atoms.
Are steam atoms different from ice 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.

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.
How do you describe the ionosphere?
The ionosphere can be described as the upper atmosphere of the planet Earth. It is made up of electrons, atoms, and molecules.
Why is the study of atoms and molecules important?
Atoms are important because they form the basic building blocks of all visible matter in the universe.
What is made of particles atoms and molecules that are too small to be seen with the unaided eye?
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.
