Question

Which of the following is an example of a diatomic molecule?

2H

O2

CH4

H2O​

Answer 1

O2

Step-by-step explanation:

Diatomic molecules are molecules that have 2 of either H,N,F,O,I,Cl, or Br. In this case, 2H is not correct because the 2 is in front of the element name. Diatomic molecules will have the two after which means that the molecule has these two elements together.
