Where does the question come from? Please remember most bonds have a mixed character, they are to some extent ionic, to some extent covalent. Are you sure there are elements which can be classified as "never covalently bonding"?
Thanks for your response Borek.
I was looking up different kinds of bonds and was curious about this specific question. I am not super familiar with the world of chemical bonds.
I think that is my question mainly, are there elements that never covalently bond?
I didn't know that it was usually a mix, so even though there is a covalent "exchange" of electrons, there is usually some other electrostatic or some other form of bond at the same time?
Atoms bond with each other and they don't care about "how" - the only thing that matters is that after they are in a more stable state. Problems start when we try to name and classify bonds - both "ionic" and "covalent" are only our approximations, some ideal states that almost never occur in the real molecules.
But they are different kids of bonds, right? Distinctly different from one another? I guess a rainbow spectrum also merges colors from one to another but there are still distinguishable colors/frequencies, and there are some places where certain spectrums don't reach.
Can a similar thing be said with covalent bonds? Or any other bonds?
I am still confused about whether certain atoms can emerge (or not) certain "types" of bonds, whatever that might mean.
Or is the idea to just talk about "one kind of a bond", with different variations?
That is super helpful, thanks DS2C!
Now are there certain elements that bond only in the "pure covalent zone", or do most atoms have some, if even super small inclination for either of the other bonds?
It seems that it might be the latter based on everyone's responses. Or am I thinking of all this all wrong?
Another thing that comes to mind, if a molecule gets created where there are more different atoms being added, I imagine that would change it's electronegativity in different parts, and as a result the "type of bond" it can create with other substances. Would that be correct?
And another final question: would that spectrum above include all the types of bonds that can exist, I've read about, Van der Waals, Hydrophobic, π-effects, would all these be somwhere in that drawing?
I think your best bet is to really look into how electronegativity works, and that will help you understand bonds. Theres really no exact answer and like Borek said there are exceptions. When I took my Intro Chemistry class I think my professor got real annoyed with me because Id always ask for absolutes and there really arent any.
