Answer:
all statements are true but scientifically depending on some assumptions
Explanation:
Each element has it's own atomic number that determine how electrons are distributed in shells. the more the shells of electrons, the bigger the atomic radius. Therefore the actual space occupied by an atom of an element fully depends on its atomic number
From the findings of Van Der Waal, the actual space occupied by a gas is less than the volume of the container. Reasons being the magnitude of the intermolecular forces between the gas molecules and volume of the molecules being almost negligible to the volume of the container
