Web8 nov. 2024 · The negative ion of Cs has the greatest radius because it has an extra electron which repels the existing electron, so the radius increases. The opposite occurs for Cs+. since it loses an electron, the entire 6th electron shell is empty, so the radius is smaller than the standard Cs. Top Nathan Tong 3G Posts: 101 Joined: Thu Oct 01, 2024 4:49 am Web26 aug. 2024 · 1 Answer. I believe the answer would be: Te2- > I- > Cs+ > Ba2+ > La3+ (from biggest to smallest) This is what you wrote above. This makes sense because all 5 ions are isoelectronic with xenon (i.e. they all have 54 electrons) but the number of protons (positively charged particles in the nucleus of the atom) of each is different: La3+ has 54 ...

Web12 dec. 2016 · Searching for a cation that is larger quickly gives potassium with 152 p m crystal ionic radius. In effective ionic radius terms (the second table), fluoride is mentioned as having 133 p m while K X + has 138 p m. Thus, by both sets of values the cation in K F is larger than the anion.
