Good afternoon, everyone, I could answer the question in chemistry correctly which is only 34% people got correctly. I think the subject of chemistry is the most difficult to learn, but I able to answer it correctly is proved that I have potential to learn the science if I have humble heart to learn. Moreover, I am good at physics including the atomic physics, so I also good at this part is normal.  In addition, many people have made the confusion between the atomic number and mass number, that is prove that chemistry is a difficult subject. For example, many people don’t understand the atomic number is a number of protons. Finally, I wish I have some chances to study , that is the end of comment in this article.
