If you put your bottle of olive oil in the fridge, it will become solid overnight.
Alkali Metals - These elements have just 1 electron in the outer shell of their atom and are very reactive. The answer is that the negatively charged electron clouds of the atoms will repel each other if they get too close together, resulting in our perception of solidity.
