Is the bond formed between each pair of atoms pure covalent (a. k.a. nonpolar covalent), polar covalent, or ionic? (a) I and I (b) Cs and Br (c) P and O

Electronegativity
Which of the following sets of elements is in the correct order of increasing atomic radius (smallest one first, etc.)?
A) Ga, Ge, As
B) B, Al, Ga
C) I, Br, Cl D) As, S, P E) P, S, C

So, look up for electronegativity table

There's a continuum for deciding whether the bond is non-polar, polar, or ionic

If electronegativity difference is less than 0.4 it's non-polar

i think the answer is a) as air pressure in an area increases, the density of the gas particles in that area decreases.
