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

Explanation:

Pls vote my answer as brainliest

1. 1 mole of anything contains 6.022x10^23 pieces  

d  

2. a  

3. c, number  

5. 1.24x10^24atoms / 6.022x10^23atoms/mole = 2moles h2 atoms  

6. fe2br3 mass = 2moles x mass fe + 3 moles x mass br  

molar mass = grams / number of moles = g/mole  

to find moles = g / molar mass  

to find mass = g = molar mass / moles

it would be a gas formation
