the ability to trap heat a tendency to lose electrons a tendency to exist as diatomic molecules the ability to bond with multiple other elements
I gave my students this multiple choice question: Which trait is common in gases that contribute to Earth's greenhouse effect?

Only one answer is correct among these 4 choices:
- the ability to trap heat
- a tendency to lose electrons
- a tendency to exist as diatomic molecules
- the ability to bond with multiple other elements

Could you tell me which one is correct?
