Among the elements of the second period Li to Ne pick out the element: (i) with the highest first ionisation energy.(ii) with the highest electronegativity. (iii) with the largest atomic radius Give the reason for your choice. |

Answer» (i) The ionisation energy increases on going from left to right. Therefore, the element with the highest ionisation energy is Ne. (ii)The electro negativity is electron- accepting tendency. This increases on going from left to right and decreases down the group. Therefore, the element with the highest electro- negativity is F. (iii)The atomic radius decreases across a period on going from left to right. Thus, the first element of any period should have the largest atomic radii. Here, Li has the largest atomic radii. |
