Very unreactive- very stable arrangements of electrons. 1 of 5 What do "shells" represent in a diagram of an atom? Energy levels. 2 of 5 In which shell will electrons in the lowest energy level be found? Closest shell to the nucleus. 3 of 5 What must electrons do first to occupy the second shell? Must occupy the lowest energy levels first. 4 of 5 What do elements in the same group have in common? Same number of electrons in the outer shell. 5 of 5
