Which elements form diatomic molecules?

$H_2$, $O_2$, $N_2$, $X_2(X=F, Cl)$... Of course there are binuclear hydrogen halides, and interhalogens...the halogens, $X_2$, feature gaseous, liquid, and solid states...

Hydrogen gas: $("H":"H")$ Fluorine gas: $("F":"F")$ Chlorine gas: $("Cl":"Cl")$

The main reason the noble gases do not need to bond with other is that their outermost subshells are filled. These are known as . Take helium for example. It...

We formally invoke a triple bond in $:C-=O$, a double bond in $O=O$, and a single bond in $Cl-Cl$. Given these representations, there are $6$, $4$, and $2$ electrons in...

Well, five of them are gases, one a liquid, and one a solid at $25^@ "C"$ and $"1 atm"$. But if you mean which ones actually are found as such,...

How so? Well, because hydrogen is by far the most abundant element in the universe as far as we know...and commonly hydrogen appears as the $H_2$ molecule... And this occurrence...

Note the state of Bromine and Iodine.

Of course, a diatomic molecule, and you should be able to quote many of these, including the ones you are breathing now, must be linear. Can you think of any...

Rememer BrIFClOHN Bromine, Iodine, Fluorine, Chlorine, Oxygen, Hydrogen and Nitrogen are the which form diatomic molecules. P.S. The H is silent when you pronounce the acronym. Noel P.

Every molecule that consists of two atoms is diatomic. Only if the two atoms are the same there is a diatomic element. So $O_2$ is a diatomic element (and thus...
