It has a negative charge emits energy when it moves to a lower energy orbit from an excited state and it has the same mass as a proton
Atomic radii increase when going down a group and decreases when going towards the anion periods. So A and D.
Osmosis and diffusion are related processes that display similarities. Both osmosis and diffusion equalize the concentration of two solutions. Both diffusion and osmosis are passive transport processes, which means they do not require any input of extra energy to occur. In both diffusion and osmosis, particles move from an area of higher concentration to one of lower concentration. Osmosis and facilitated diffusion both account for movement of molecules from a region of high concentration to a region of low concentration.
