I can't exactly answer this question because it is not the image of the rating given. In order to help you, I just say how the notation is to be interpreted.The general notation shown in the attached image. E stands for any element in the periodic table. And represents the atomic number of the element, or the number of protons in the nucleus. X is the mass number, or the number of neutrons and protons in an element. The and and the atomic number of the element And must match. You can use the periodic table as a guide.
