How does fluorine (F)differ from iodine(I)

A. Fluorine (F) has 3 more energy shells than iodine (I).

B. Fluorine (F) has 1 less energy shell than iodine (I).

C. Fluorine (F) has 1 more energy shell than iodine (I).

D. Fluorine (F) has 3 less energy shells than iodine (I).

Sagot :

I believe your answer is D. Fluorine (F) had 3 less energy shells than iodine (I)
Fluorine has 2 energy shells while iodine has 5 energy shells.
Subtract 5-2=3

Fluorine (F) and iodine(I) are the halogen elements that belong to group 17. They differ from each other as fluorine has 3 fewer energy shells than iodine. Thus, option D is correct.

What are halogen groups?

Halogen is a nonmetallic element that belongs to group 17 and consists of six elements namely fluorine, bromine, tennessine, chlorine, astatine, and iodine.

They are diatomic and have 7 valence electrons in the outer shell, which makes them highly reactive and electronegative. The shielding effect is less in F than I due to the closer placement and attraction of the valence electron to the nucleus.

Fluorine differs from iodine as it has a smaller size with fewer energy shells than iodine. Iodine has five energy shells,  whereas fluorine has two energy shells that make the difference of three shells between them.

Therefore, F and I differ from each other.
