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.
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.
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.
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.
Cation is always smaller than corresponding neutral atom.
No, since electrons are part of an atom, they are smaller -- much smaller. In fact, they weigh practically nothing.
The model of an atom is larger than the actual atom itself. Atom models are simplified representations used to help understand the structure and behavior of atoms at a scale that is easier for us to comprehend.
A chloride ion is larger than a chlorine atom because it has gained an electron, leading to increased electron-electron repulsion and a larger ionic radius compared to the atomic radius of a chlorine atom.
