If there is an extra electron in the valence level then the electron is in the excited state and is carrying more energy. If the atom is normal then it is in the ground stte and contains low energy.
The second energy level contains eight valance electrons when it's full.
first energy level contains only S shell that can accomadate 2 electrons where as 2nd energy level contains S shell and P shell as well which can accomadate 2 and 6(3X2) electrons respectively..so the answer is 8 for 2nd energy level. (or) No.of electrons in any main energy level = 2n2 Here n = orbit (or energy level) number In our question , n = 2 No.of electrons in 2nd energy level = 2(2)2 = 8
The lowest energy level that has F orbitals is the fourth energy level. The Atomic orbital of any atom only contains 2 electrons.

The valance energy level contains 4 electrons in carbon.
The total number of electrons in Phosphorus (P) is 15 (its atomic number). The first energy level contains 2, the second energy level contains 8, and the third energy level contains 5.
It contains electrons, neutrons, protons, and energy.

The innermost energy level always contains two electrons and the rest are arranged in 8s. for example the energy levels of calcium- 2,8,8,2. calcium contains 20 electrons. once the energy levels are filled upto 8 electrons then we move from onto the next energy level. hope this makes sense lol :)
It contains kinetic energy mainly. Potential energy is relative to its position

Noble gases (except for helium which has 2 valence electrons).
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.
