Questions with what I think correct:

-Has the largest anion.D
-Is the most electronegative.A
-Has the highest bonding energy in its diatomic molecule.B
-Is a liquid at room temperature in tis free state.C

Chooses:
A. Fluoride
B. Chloride
C. Bromide
D. Iodine

Please can somebody double check this for me...

Yes, that is correct.

Some picky points.
The most electronegative element is fluorine, not fluoride.
The highest bonding energy is chlorine, not chloride.
The liquid at room T is bromine, not bromide.
I know you just copied what was in the problem so the problem is at fault but I wanted to be sure you were aware of the differences.

Thank you for pointing out those picky points. You are absolutely correct.

To determine the correct answers, we need to consider the properties of the given elements: fluorine (F), chlorine (Cl), bromine (Br), and iodine (I).

A. Fluoride: Fluoride is the anion of fluorine, which is the most electronegative element on the periodic table. Therefore, it satisfies the condition of being the most electronegative (choice A).

B. Chloride: Chloride is the anion of chlorine. Chlorine has a higher bonding energy in its diatomic molecule compared to fluorine, bromine, and iodine. Therefore, it satisfies the condition of having the highest bonding energy in its diatomic molecule (choice B).

C. Bromide: Bromide is the anion of bromine. Bromine is a liquid at room temperature and pressure in its free state. Therefore, it satisfies the condition of being a liquid at room temperature in its free state (choice C).

D. Iodine: Iodine itself is a solid at room temperature and pressure, so it does not satisfy the condition of being a liquid at room temperature in its free state. Therefore, it cannot be the correct answer for choice D.

In conclusion, the correct answers are:

A. Fluoride - Most electronegative (correct)
B. Chloride - Highest bonding energy in its diatomic molecule (correct)
C. Bromide - Liquid at room temperature in its free state (correct)
D. Iodine - Incorrect choice (not a liquid at room temperature in its free state)
