an atom is larger than an electron
Anion will have more electron than which atom it was form. So, after forming the the atom will have more electron cloud and size will be smaller compare to the original one.
A cation is smaller than the neutral atom because one electron is removed from the original atom to form it. An anion is larger than the neutral atom because one electron is added to the original atom to form it.
It is impossible to know exactly where an electron is. Thus, the size of an electron cloud can be given only in terms of probability. Even then, the size of the electron cloud depends on how many electrons an atom possesses.
When an electron is added to an atom, its size increases due to increase in repulsions between the electrons.
Only the anion is greater than the atom because gained an electron.
It shrinks loosing an electron.

electron is the smallest
The ATOM decreases in size when it loses an electron and increases when electrons are added.
The physical size of an atom is largely determined by the size of the electron cloud.
the electron
It grows smaller in size.
If the electron were the size of a golf ball, the proton would be about the size of a basketball and the electron would be orbiting about 8000 meters away (assuming the Bohr model of the atom).
I need to know also

Think of the sun as the nucleus and the oort cloud (past pluto) as where the electron orbitals start. The size (volume) of the nucleus is tiny compared to the size (volume) of the atom (defined by the extent of the electron cloud).
