Well, it seems that there are 2 types of groups. Because one is completely red and the other one is kinda blurry so No. Even tho atoms bond together to form different shapes and size looking of molecules.
They aren't because 99% molecules that ARE the same all LOOK the same, and some of them have 2 white things, some have 1, and some i see even have 3. so i would definitely say that no, they aren't all the same
