the first one because it is closer to the nucleus. :)
The energy levels and orbitals the electrons are in
The principal quantum number describes the size of the orbital. Because they have opposite electrical charges, electrons MORE.
Sub shells or sub energy levels, s,p,d,f , they are represented by Azimuthal quantum number 'l'.
These are: principal quantum number (n), azimutal quantum number (ł), magnetic quantum number (m), spin quantum number (sd).
Discrete energy levels (eigenvalues) in atoms (noticed by experiments in spectroscopy) could not be explained by Newtonian Mechanics. Also, the wave-like nature of electrons (eg: diffraction) indicated the first signs of wave-particle duality. These were the first clues.
The quantum number relating to the size and energy of an orbital
by the quantum number n. if n=1 energy level is at 1 if n=2 energy level is 2 for example 2s1
The energy levels and orbitals the electrons are in
the inner energy level of an atom has a maximum # of
The principal quantum number describes the size of the orbital. Because they have opposite electrical charges, electrons MORE.
The period number tell about the energy levels occupied by electrons
Chloride is an ion, not an atom. It has 18 electrons which are 2, 8, 8 in the first three quantum levels respectively.
The quantum number for that energy level.

Sort of but not exactly.A neutral isolated atom of boron has, nominally, three occupied electronic energy levels (1s, 2s, and 2p).However, it has an infinite number of unoccupied energy levels (as do all atoms).Also, in compounds, there's a strong tendency for the 2s and 2p orbitals to "hybridize", forming sp, sp2, or sp3 orbitals, each of which has its own characteristic energy level.Boron does not have three energy levels. If you know the element's principle quantum number, then you can find how many electrons can fit in an atom of a specific element. In this case, Boron can only store 2p1/2 (p is the principle quantum number) electrons. This is getting too complex, and isn't required for you to know as of this exact moment. The answer is that Boron only has two energy levels.
