Vedclass · Answer

(C) $I.$ An anion is formed by the gain of electrons. Since the number of electrons increases while the number of protons remains constant,the effective nuclear charge per electron decreases,leading to an increase in the ionic radius compared to the parent atom.$II.$ Across a period,the atomic number increases,which increases the effective nuclear charge. This results in a smaller atomic size and a stronger attraction between the nucleus and the valence electrons,thereby increasing the ionization energy.$III.$ Electronegativity is defined as the tendency of an atom in a chemical compound to attract a shared pair of electrons,not an isolated atom. Therefore,statement $(III)$ is incorrect.Thus,statements $(I)$ and $(II)$ are correct.
