Description : The elements of the third period of the Periodic Table are given below: periodic-classification-of-elements-chapter-wise-important-questions-class-10-science-1 (a) Which atom is bigger, Na or Mg? Why? (6) Identify the most (i) metallic and (ii) non-metallic element in Period 3. -Science

Last Answer : (a) Sodium is bigger than magnesium as it has lesser nuclear charge so there is less force of attraction between nucleus and valence electrons and less effective nuclear charge. It is, therefore, ... the most non-metallic element because it can gain electrons easily due to its smallest atomic size.
