Period 3 & Na Mg Al Si P s al
p) Which atom is bigger among Na or Mg? Why?
q) Identify the most (i) metallic and (ii) non-metallic element in Period 3.​

Answer 1

Answer:

Explanation:The ionization energy of the elements within a period generally increases from left to right. This is due to valence shell stability. The ionization energy of the elements within a group generally decreases from top to bottom. This is due to electron shielding.
