For example iron is really dense and it’s density seems to be the reason it’s such a strong material, why is the same not true for chalk?
I looked at a chart and chalk is much more dense than so many other types of rock, all of which are much stronger than chalk and could be used practically as building materials etc. But chalk is so soft? Is it because of the porosity? Or structure? Idk

Mercury is a lot more dense. But try holding it in your hand to compare with Iron or chalk and u will quickly realyse densety has nothing to do with strengh (sincr mercury in your hand will be a licquid… btw, let i be a thought experiment OR use real fucking good protective gear!)
Strengh is about how strong/weak the bonds BETWEEN the molecules hold together. Densety is just how tight it can be packed (like how many nuclear particles it has, meaning a fairly high weight with harldy a bigger nuclear size, or how snug the molecules can sit (but it could still mean the molecules could slide between themselfs if the Bonds isnt strong to hold them togherer)
Styrofoam is stronger than water, yet water is heavier. Diamonds is the strongens natural mineral there is, because the 4 bonded carbon structure is SO rediculus strong, yet carbon is pretty light element so most materials will have a higher DENSETY than diamonds – Iron, steel (a compound material of iron and a little carbon), gold, titanium, or uranium (a quite heavy element) are all weaker and more dense than diamonds.
