Place the following substances in order of increasing boiling point. Ne Cl2 O2

a. O2 < Cl2 < Ne
b. Cl2 < Ne < O2
c. Cl2 < O2 < Ne
d. Ne < O2 < Cl2
e. Ne < Cl2 < O2

= D

Explanation:

The atomic mass increases from Ne to O2 to Cl2 hence the boiling point also increases, therefore

Ne < O2 < Cl2

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
