most of the alpha particle pass through the gold foil without deviation and the mass of electron are very small
Around 1909
yes.
They traveled through the empty spaces of the gold foil.
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 inter molecular spaces
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.

anything that soaks up moisture anything that soaks up moisture (a sponge has air spaces that contain the water) mostly anthing that has air space (very small air spaces)
No.
no
Cranial bones contain air spaces. These air spaces are known as skeletal pneumaticity. Bird bones are all filled with air spaces.
They traveled through the empty spaces of the gold foil.
The spaces between the trabeculae do contain red or yellow marrow. This depends on a person's age and on which bone it is.
No, gases have more empty spaces.
Yes. Names can contain letters, digits, and spaces, as well as most of the punctuation symbols.
Marrow
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.
