Question
Give reasoni. Anion is bigger in size than atom.ii. Isotopes have similar chemical properties
Solution
i. Anions are larger in size than their parent atoms because they have gained extra electrons. These additional electrons increase the electron-electron repulsion in the electron cloud, causing it to expand and thus increasing the size of the anion.
ii. Isotopes have similar chemical properties because they have the same number of electrons and the same electronic configuration. Chemical properties are determined by the arrangement of electrons, particularly the valence electrons, and not by the number of neutrons. Therefore, isotopes of the same element will have the same chemical properties.
