Answer: Dobereiner arranged selected things with comparable Homes in groups of three in this kind of way that the atomic mass of the middle ingredient was practically the same as the common atomic masses of the very first and third things.
Since the anion is fashioned by getting a number of electron. Therefore, the atomic radius is larger sized compared to the corresponding atom.
Response: (i) The helpful nuclear cost of magnesium is greater than that of sodium. For these motives, the energy needed to clear away an electron from magnesium is much more than the Vitality required in sodium. Therefore, the 1st ionization enthalpy of sodium is reduce than that of magnesium.
