Question

O
(d) f
Q3. Which of the following elements
has the maximum negative electron
gain enthalpy?
*
O (a) Oxygen
(b) Chlorine
O (c) Fluorine
(d) Nitrogen
Q 4.In which of the following​

Answer 1

Explanation:

Halogens have the highest negative value of electron gain enthalpy. Here Cl and F both are halogens but electron gain enthalpy of Cl is more negative than F because of the very small size of F which causes interelectronic repulsion among its electrons. 

Cl has the most negative one. P has the least negative one due to the larger size.  

Answer 2

flourine has the maximum negative electrons
