Question

question 7 6 pts a nonpolar covalent bond will form between which two atoms as shown in the following combinations? potassium and chlorine hydrogen and chlorine sodium and bromine chlorine and chlorine question 8 6 pts as the difference in electronegativity between two atoms increases, the polarity of a bond between those two atoms increases. decreases. remains the same.

Explanation:

• For Question 7: A non - polar covalent bond forms between atoms with the same electronegativity. Chlorine and chlorine have the same electronegativity. In the other options, there are metal - nonmetal or non - metal combinations with different electronegativities leading to polar or ionic bonds.
• For Question 8: The polarity of a bond is directly related to the electronegativity difference between two atoms. As the electronegativity difference increases, the polarity of the bond increases.

Answer:

• Question 7: chlorine and chlorine
• Question 8: increases.
