Elements other than carbon that can form many different compounds by bonding to themselves?












11












$begingroup$


My textbook says the following:




Unique among the elements, carbon can bond to itself to form extremely strong two-dimensional sheets, as it does in graphite, as well as buckyballs and nanotubes.




Is carbon the only element that can do this?



If not, then what are the other elements can also do this? Is there a term to describe such elements?



What is the chemical characteristic that allows this to occur?



I would greatly appreciate it if people could please take the time to clarify this.

    The right question isn't whether an element can bond to itself. Plenty do that. The issue is whether an element can form a wide variety of stable structures when bonded to itself.

    What is the actual question here? Your citation does not say that bonding between identical atoms is something unique - every single element could do this even if transiently. The point is that carbon carbon allotropes are somewhat exceptional.

Is carbon the only element that can do this?




No, carbon is not the only element with such characteristics.




If not, then what are the other elements can also do this?




There is a whole number of elements such as silicon, arsenic, germanium.




Is there a term to describe such elements?




At least I'm unaware of such a term, which might be furnished by our far wiser community.




What is the chemical characteristic that allows this to occur?




Catenation.



More information:



According to the Molecular Orbital Theory, the condition for a compound to exist is that it should have more electrons in the bonding orbitals than in the anti-bonding orbitals. So, as long as you have the bonding orbitals filled more, you can have pretty anything, more than just chains of atoms.



Thus, the existence of a compound also depends on the precise conditions in which the compound is kept, for example sodium forms different types of chlorides under different conditions and that as pointed out by Poutnik in the comments, $ce{He2^1+}$ and a ton of others are discovered and still more awaiting discovery.

    No, carbon is not the only one that can bond to itself. It's a unique property of some elements mainly the group 14 elements like silicon, germanium, arsenic etc. This phenomenon is called catenation. It might be mainly due to presence of four valence electrons in their outermost shell. A large number of carbon atoms are linked with each other with sigma and pi bonds. However catenation gets limited as we move down the group in group 14.

      So most of this has been answered, but the main elements that can bond to themselves are called diatomic atoms. This includes hydrogen, nitrogen, fluorine, oxygen, iodine, chlorine, and bromine. There are other elements that can do this as well, however these main elements occur naturally in their diatomic state as gases.

        "Diatomic atom" is a weird term, diatomic molecule makes way more sense. Besides, the way the answer is formulated, it appears to me that all elements that are capable of self-bonding are diatomic molecules, whereas in reality diatomic molecules is a tiny subset of the former.

                        "Diatomic atom" is a weird term, diatomic molecule makes way more sense. Besides, the way the answer is formulated, it appears to me that all elements that are capable of self-bonding are diatomic molecules, whereas in reality diatomic molecules is a tiny subset of the former.

                        It's pretty clear that the question is asking about self-bonding beyond simple diatomic molecules.

                      So most of this has been answered, but the main elements that can bond to themselves are called diatomic atoms. This includes hydrogen, nitrogen, fluorine, oxygen, iodine, chlorine, and bromine. There are other elements that can do this as well, however these main elements occur naturally in their diatomic state as gases.
