A positive ion is smaller than its parent atom because it has less electrons than its parent atom. The reduced number of electrons are then pulled more tightly to the positive nucleus because the number of protons remains the same, and these now exceed the electrons in number.
A positive ion is generally smaller in size than the neutral form from which it forms. This is because when an atom loses an electron to become a positive ion, the remaining electrons experience a stronger attraction to the nucleus, leading to a more compact arrangement.
A negative ion is typically larger than its parent atom. When an atom gains an electron to become a negative ion, the added electron increases the electron-electron repulsions, causing the electron cloud to expand. This expansion results in a larger ionic radius compared to the neutral atom.
In general, a cation is smaller than its parent atom because it has lost one or more electrons, leading to a decrease in electron-electron repulsion and a smaller electron cloud.

When an atom loses electrons, it becomes smaller in size because there are fewer negatively charged electrons in the electron cloud to balance the positive charge of the protons in the nucleus. This results in a stronger attraction between the remaining electrons and the nucleus, causing the electron cloud to contract and the overall radius of the atom to decrease.
A positive ion is generally smaller in size than the neutral form from which it forms. This is because when an atom loses an electron to become a positive ion, the remaining electrons experience a stronger attraction to the nucleus, leading to a more compact arrangement.
A negative ion would be considered larger than its parent atom. This is because electrons have mass, which makes the ions gain mass to outgrow their parent atoms.
A negative ion is typically larger than its parent atom. When an atom gains an electron to become a negative ion, the added electron increases the electron-electron repulsions, causing the electron cloud to expand. This expansion results in a larger ionic radius compared to the neutral atom.
In general, a cation is smaller than its parent atom because it has lost one or more electrons, leading to a decrease in electron-electron repulsion and a smaller electron cloud.
The positive ion has donated an electron to another atom making the other atom a negative ion and much larger in radius. The positive ion is now much smaller in radius.
Smaller
Larger.
Adding more protons to an atom would make it smaller. This is because the increased positive charge from the protons will attract the negatively charged electrons more strongly, pulling them closer to the nucleus and reducing the size of the atom as a whole.
