Answer:
option 1, option 2, and option 3, and option 5 all technically work.
If the teacher/grader only accepts two options, pick option 1 and 5.
if your teacher only accepts 3 options, pick 1, 2, and 5
Step-by-step explanation:
If we can find an example of a molecule with atoms of those electron configurations, the combinations can produce molecules.
For option 1 we pick hydrogen and fluorine, which can form HF
For option 2 we pick oxygen and oxygen, forming O2
For option 3 pick nitrogen and oxygen, which forms the radical NO (though it is quite stable on its own)
For option 4 if we pick hydrogen and magnesium, MgH2 would be formed, which would require 2 hydrogen (ns1) atoms, so option 4 might not work depending on what exactly the question is asking
For option 5, magnesium and sulfur form MgS.
