most of the alpha particle pass through the gold foil without deviation and the mass of electron are very small
Porous rock formations, such as limestone or sandstone, contain spaces within their structure that allow water to sink in. These spaces, known as pore spaces, enable water to flow through and be absorbed by the rock.
Insulating materials contain spaces with air because air is a poor conductor of heat compared to solid materials. These air pockets help to reduce heat transfer through conduction and convection, making the insulating material more effective at keeping warmth in or out.
The vast majority of alpha particles passed through the gold foil without being deflected, as the atom is mostly empty space. However, a small fraction of alpha particles were deflected at large angles, indicating the presence of a dense, positively charged nucleus in the atom.
Ernest Rutherford develop the idea that the atom has nucleus by using gold foil and alpha particles. Basically He shot the poistive laser to the gold foil which contains positive and negitive, and he saw the reflection of it and it tells us that there is positive charge to reflect positive laser with is proton. J.J Thomson already discover the electron, who has negative charge. Then Rutherford figured out the nucleus is positive.
Because it was something they could get very thin. They wanted to see how atoms interacted with each other... because if some got through and some didn't it would mean there were a lot of spaces between the atoms, but if the foil was too thick it would defeat the purpose.
The atomic model that contained empty spaces within it was given by Mendeleev. The gaps were left for the elements that were not discovered at that time.

No, gases have more empty spaces.

Not necessarily. Scoria and pumice are forms of volcanic glass that contain air spaces, while obsidian, another volcanic glass, contains minimal air spaces if any.
