You are missing the initial structure, but in picture 1 you have the structure which I found on another place.
Now, as you can see in picture 1, you have a diene, which are two rings with 4 doubles bonds, however, only two of them, in the second ring are conjugated, therefore, the reaction will take place there. This is a Diels Alder reaction, so the mechanism is pretty easy. Picture 2, shows the product obtained after the reaction.
The number of protons, neutrons, and electrons in an atom can be determined from a set of simple rules. The number of protons in the nucleus of the atom is equal to the atomic number (Z). The number of electrons in a neutral atom is equal to the number of protons.
