The seven energy levels that are known to exist can hold a total of 118 electrons. In order from one to seven, they are 2, 8, 18, 32, 32, 18, and 8.
It depends on what element the atom is. For example if it is Hydrogen it has one ring or energy level. The higher the element's atomic number is on the periodic table the more energy levels it will have.Actually, every atom has an infinite number of energy levels. Yes, hydrogen has as many as plutonium or gold. The difference is how many of these levels are filled with electrons. When asking about how many filled electron levels an atom has, it increases with atomic number.
All halogens (fluorine, chlorine, bromine, iodine and astatine) have 7 valence electrons.
An atom with seven electrons will have five electrons in the second energy level.
There are 7 Energy Levels of electrons called shells, and there are 4 sub-shellsnamed as sub-shells s, p, d, and f. They are ordered as 1s - 2s - 2p - 3s- 3p - 4s - 3d - 4p - 5s- 4d - 5p - 6s - 4f - 5d - 6p - 7s - 5f - 6d - 7p - 6f - 7d - 7f. "s" sub-shells consists of 2 electrons, "p" sub-shells consists of 6 electrons, "d" sub-shells consists of 10 electrons, and "f" sub-shells consists of 14 electrons. The first shell has 2 electrons, the second shell has 8 electrons, the third shell has 18 electrons, the fourth shell has 32 electrons, the fifth shell has 50 electrons, the sixth shell has 72 electrons, and the seventh and last shell has 98 electrons. Oh!!! By the way, the formation of the energy levels is like the solar system. The sun is the nucleus and the proton while the Planets are the electrons. There are seven orbits and each orbit has its own electron count. I mentioned it earlier in this answer of mine.
Group seven elements have 7 electrons in their outermost energy level.
It depends on the ground level and its orbital axes
The electrons in actinium are disposed on seven energy levels.
The electrons in actinium are disposed on seven energy levels.
The electrons in actinium are disposed on seven energy levels.
Fermium has seven electron shells.
1s orbital 3P, 5d, and 7f in discovered elements

F, Cl, Br, I, At and Uus Atomic number 117 highly radioactive and unstable. So the answer is 5 naturally occurring and 1 nuclear synthesized
All halogens (fluorine, chlorine, bromine, iodine and astatine) have 7 valence electrons.
All member of the same period share the same number of energy levels. The energy levels range from one up to seven.
Halogens have six valence electrons in the outermost energy level.
An atom with seven electrons will have five electrons in the second energy level.
