Question

question 19
as the electronegativity difference increases between two nonmetal atoms, the ______ character of the bond increases.
nonpolar
covalent
conjugated
ionic
question 20
ions comprised of two or more nonmetal atoms are called ______.
polyatomic ions
hydrophilic ions
nucleophilic ions
hydrophobic ions
electrophilic ions

Explanation:

For Question 19, as electronegativity difference between non - metal atoms increases, electrons are more unevenly shared, approaching the nature of electron transfer in ionic bonds. For Question 20, by definition, ions made up of two or more non - metal atoms are polyatomic ions.

Answer:

Question 19: D. ionic
Question 20: A. polyatomic ions
