Question

In the two diatomic molecules, which end of the molecule is positive relative to the other end?

1.) Chlorine Monoflouride, ClF

2.) Iodine Monochloride, ICl

and what if both are negative? how do you answer the question? =/

Answer 1

F is the strongest, so 1. Cl will be the positive end
Cl is the strongest, so 2. I will be the positive end

In O2, N2, Cl2, F2 H2, Br2, I2, the electrons are shared evenly.
Halogens are all electronegative, but they are strongest on the top of the column, decreasing as you go down

Answer 2

1. Chlorine is positive
2. Iodine is positive.

While they both are usually (electro-)negative, their electronegativity in relation to the anion is less, meaking them anions.
