Answer:
Osmosis is the diffusion of water molecules across a permeable membrane from an area of higher concentration of water molecules to an area of lower concentration of water molecules concentration until equilibrium is reached
The atomic number of an atom is the number of protons it has, and if the atom is neutral, it will also be the number of electrons. Therefore:
The atom you're talking about has 103 protons, and an atomic number of 103.

Passive diffusion is a form of passive transport and a type of diffusion by which particles from a high concentration gradient passes through a biological membrane to a low concentration gradient. Diffusion, or simple diffusion on the other hand, is the passage of molecules without the need of a membrane.
