A molecule made of two identical atoms is called diatomic.

Five diatomic elements exist as gases at room temperature (25oC/298K) and atmospheric pressure:

  • Hydrogen, H2
  • Nitrogen, N2
  • Oxygen, O2
  • Fluorine, F2
  • Chlorine, Cl2

One diatomic element is a liquid at room temperature and atmospheric pressure:

  • Bromine, Br2

One diatomic element is a solid at room temperature and atmospheric pressure:

  • Iodine, I2

What particles are molecules made of?

Molecules are made of atoms that are bonded together. These atoms can be the same element, such as in oxygen gas (O2), or different elements, such as in water (H2O). The bonds that hold atoms together in a molecule can be covalent, ionic, or metallic.


What are molecules made up of?

Molecules are substances consisting two or more atoms.


Do atoms and molecules mean the same thing?

Molecules are made out of atoms, without atoms there are no molecules. Charged molecules (ions) will form compounds as elements do, by combining in whole-number ratios with the ions of other elements and compounds.


Is an atom more complex than a molecule?

An atom is and element. Atoms are the simplest particles of an element. A bar of pure gold is composed of gold (Au) atoms. In a sense then, the atoms that make up this bar of gold are simpler than the entire bar. However, the terms "atom" and "element" describe different levels of magnitude. An atom is a single particle of an element. An element is a pure substance composed of atoms, not compound molecules.


Are atoms composed of two elements?

Molecules of most elements are made up of only one of atom of that element. Oxygen, along with nitrogen, hydrogen, and chlorine are made up of two atoms.


Are atoms and molecules the same in terms of their composition and structure?

No, atoms are the basic building blocks of matter, while molecules are made up of two or more atoms bonded together. Atoms are the smallest unit of an element, while molecules are the smallest unit of a compound.
