Diatomic Elements
  • Hydrogen (H2)
  • Nitrogen (N2)
  • Oxygen (O2)
  • Fluorine (F2)
  • Chlorine (Cl2)
  • Iodine (I2)
  • Bromine (Br2)
Mnemonic devices
  • Made easy to remember think BrINClHOF (like a last name Brinclhof)
  • If you highlight N, O, F, Cl, Br, I; six of the seven diatomic elements on a Periodic Table - they form the number 7. The 7th is hydrogen.
  • Use the acronym I Bring Clay For Our New Home:
I = Iodine

Bring = Bromine

Clay = Chlorine

For = Fluorine

Our = Oxygen

New = Nitrogen

Home = Hydrogen

  • Just remember that all the elements that end in -gen are diatomic, considering the elements that are in the halogengroup (F, Cl, Br, I) excluding At.
  • You can also remember it by: BROHNFICL or HOFBrINCl (hoff - brincle)
  • Another one which is very easy to remember is Have No Fear Of Ice Cold Beer. Students always seem to remember this one.

Is F2 liquid is element or molecule?

If you mean F2 (fluorine), it is a diatomic molecule of the element fluorine. It's the common form of pure fluorine, since the halogen elements are all diatomic molecules.


What atoms exist as diatomic molecules?

The atoms that exist as diatomic molecules at room temperature and pressure are hydrogen (H2), nitrogen (N2), oxygen (O2), fluorine (F2), chlorine (Cl2), bromine (Br2), and iodine (I2). These atoms bond with another atom of the same element to form stable diatomic molecules.

Is sodium diatomic?

Sodium is not diatomic. Sodium is a metallic element that typically exists as individual atoms in its elemental form. Diatomic molecules, on the other hand, are molecules made up of two atoms of the same element bonded together. An example of a diatomic molecule is diatomic oxygen (O2).

Nitrogen is a gas and exists in diatomic molecule in atmosphere in its natural form.It is N2.


What is the smallest molecule?

Well, if we define a molecule as something that has more than one atom, the smallest molecules would be diatomic molecules (molecules with two atoms). The smallest diatomic molecule is hydrogen gas, H2, which consists of two protons and two electrons. Other common diatomic gases which have more electrons and more massive nuclei are O2 (oxygen), NO (nitrogen oxide), and CO (carbon monoxide).
