Explanation:
When Rutherford did the Gold Foil experiment, he expected that most of his alpha particles will go straight through, without any major deflections. He noticed that, during the experiment, most alpha particles went straight through, but was surprised to see that some got deflected by major angles. So he came up with a theory which states that every atom has got a nucleus, and also stated that most parts of the atom are empty, as most of the particles went through.

Answer:
The particle of a gas are very far apart from each other.
Explanation:
The states of matter comprises of solid, liquid and gas. The molecules of gas are free because they are not tightly held together by molecular force. The force between the molecules has been broken, hence the particles possesses the freedom to move about thereby possessing high kinetic energy (energy possessed by a body due to its motion). Since this molecules can easily move freely, they are always far apart from each other under ordinary temperature and pressure.
Answer:
its something that hold the air for forceing liy by the exgen
