larger...a negative ion has an electron added that the neutral atom does not have.

on account that a sodium ion has lost its outer electron which occupied the valence shell (outer electron shell) it rather is smaller than the sodium atom. They the two have in truth the comparable mass, regardless of the undeniable fact that, because of the fact electrons are rather much massless in comparison to protons and neutrons. Atoms that income electrons are greater desirable than their discern atom.

it will be the same because the atom only receives the electrons to have enough electrons to reach the balance (8 electrons at the highest level), not to enlarge the radius of the atom

radius of neutral is smaller(if we measure the size of the ion including the electronic effect(orbitals)),if we dont include the orbitals,then the size is the same.
