WebSep 2, 2024 · Answer: Halogens have 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 very small size of F which causes interelectronic repulsion among its electrons. P has the lest negative one due to larger size. Please Mark As Brainliest... And Follow Please... Web10 6 2 14 10 6 2 14 10 6 4 d , 5 p , 6 s , 4 f , 5d , 6 p , 7 s , 5f , 6d , 7 p 30. Orbital notation- There are 4 orbital’s; the s, p, d, and f. The s is round shaped and holds 2 electrons; the p is dumbbell shaped and holds 6 electrons. The d and f are complex shaped and hold 10 and 14 electrons respectively.
