Among the elements of second period i.e. from Li to Ne, pick out the elements:

(a) with the highest first ionisation enthalpy
(b) with the highest electronegativity
(c) with the largest atomic radius
(d) which is the most reactive non-metal
(e) which is the most reactive metal ?

Solution

The elements of the second period are:
Li, Be, B, C, N, O, F, Ne
(a) The element with highest first ionisation enthalpy: Neon (Ne).
(b) The element with highest electronegativity: Fluorine (F).
(c) The element with largest atomic radius: Lithium (Li).
(d) The most reactive non-metal: Fluorine (F).
(e) The most reactive metal: Lithium (Li).
