What are two elements that have an attraction for each other?
what are two elements or compounds (liquid) that have a big attraction for each other? That can't be seperated from each other through physical means
but only from chemical reactions?
or require a lot of strength to be removed from each other. A LOT OF STRENGTH.

Bromine and cesium. Bromine is liquid at room temperature, Cs is liquid at 30 C or so. When you mix the two you will have a VERY strong reaction and
the resulting salt, CsBr, is very hard to make into its composing elements.

so If i applied bromine on one end of a wooden block and cesium on another will I be able to physically pull them apart after the reaction?
Also i'm looking for something that is less reactive.

If they're on opposite ends of the block, they won't be reacting.
Unless you mean.... two blocks, substances meet in middle?
Gotcha. If you're looking for macroscopic effects, you're looking for glues.

well no superglue really works for me right now, i'm trying to attach two cotton objects together and when superglue touches cotton it might ignite it
and it gives off this awful smell and it irritates my eyes. (probably a reaction from cotton and superglue) I have used almost all of the current
glues and was wondering if you might tell me some elements that give off that "macroscopic effect" and those elements haven't been used yet for glues.

Teflon.
It's just carbon with lots of fluorines all over every single bond position it has.
Which is why it's chemically bulletproof.
In terms of pure elements, nitrogen to nitrogen.
{edit}
Right, two cotton objects. I'm not sure why you'd need a super strong bond for that given that the cotton is super soft by comparison but... epoxy
glue. Epoxy paints are used industrially where the surface needs to be super resistant to damage and things being spilt on it.
Watering the epoxy down with an appropriate solvent, or using a casting / modeling form that's already runnier, will help it penetrate the cotton
better.

One.... What objects are are you trying to glue together? And why?
Two.... Superglue generally will not cause cotton to ignite.
Three.. Superglue vapor always irritates the eyes.

It irritates me in general, because I usually end up with spoons and pencils stuck to me.

Consider yourself
lucky.
A quick google indicates that super glue has been mistaken for:
1. Lip balm
2. Preparation H
3. Eye drops

My mum has managed to drink Stardrops Ammonia cleaner thinking it was grapefruit juice; same colour. Considering it contains (or at least I think it
used to) Bitrex, that it makes me feel better about not liking grapefruits.
That, or it was an attempt at suicide.

VX is a pretty good adhesive, but only true badasses use it for that purpose.

Peach, your mother is why the rest of us can't have nice things.
Nothing personal against yer mum, but the sad thing is there are many people who would do that...... more than once.

I swear it says Zirconium more on that wiki page than it does of the title element.

CsF, just get some fluorine liquid (cold) and some cesium and get them in contact, then try to get your fluorine gas back with a hammer or a vice,
you'll struggle i believe.

a.) Homework that's already been handed in
b.) Someone trying to design something who can't specify a glue and isn't really that bothered based on the lack of response
c.) Someone who isn't really that bothered

Have fun working with elemental fluorine...
