Explain why size of cation and anion of an element is different from its parent atom

Answer 1

hey there!!
☯️why size of cation and anion of an element is different from its parent atom?

✴️✴️As a consequence, cations are smaller than their parent atoms, as illustrated in Figure 8.5 . The opposite is true of negative ions. When electrons are added to form an anion, the increased electron-electron repulsions cause the electrons to spread out more in space. Thus , anions are larger than their parent atoms.
