These are the valence electrons.
valence shell
Electrons in the outermost shell are called valence electrons.
Electrons in the outermost energy shell (valence shell) have the most energy.
All of them. The s1 shell is the outermost electron shell. Despite being the first shell quoted and the lowest in energy, it is actually the largest in average diameter, and so is the "outermost."
Electron Shells
The question is somewhat vague. If the question were written as an atom contains seven electrons in the outermost energy level and that outermost shell is a p-shell then the atom is a halogen. If the atom contains seven electrons in the outermost energy level and that outermost shell is a d-shell or f-shell then the atom is a metal.
If you are referring to the valence shell; the answer is one.
As a neutral atom, sodium possesses 1 electron in its outermost (3rd) energy level. As a 1+ ion, it possesses 8 electrons in its second energy level, forming an octet, which is the optimum number of electrons for sodium to possess in its outermost energy shell.
An oxygen atom has eight electrons. The first electron shell can contain two electrons so that shell is filled leaving six electrons left. Since the second electron shell can contain up to eight electrons, the remaining six electrons go into the second shell. Since the second shell is the outermost shell, there are six electron's in the outer energy level.
Outermost energy level is full if there are 8 electrons in the valence shell.
