Primary Quantum number n represents the shell in which the electons are filled .
These shells are K,L,M ,N O, P ...........
They are of of course the energy levels .
Again the energy of the orbital is determined by the sum of (n+l)
which is the sum of principal quantum number as well as Azimuththal quantum number
in this way the electrons are filled in the increasing order of energy
1s<2s<2p<3s<3p<4s<3d<4p<5s<4d<5p<6s<4f<5d<6p<7s<5f<6d<7p<8s................

What is a principal quantam number?
The principal quantum number refers to the electron shell, or energy. Refer to the related link to read a Wikipedia article about quantum numbers.
What is a quantum number?
Four quantum numbers are used to describe electrons. The principle quantum number is the energy level of an electron. The angular momentum number is the shape of the orbital holding the electron. The magnetic quantum number is the position of an orbital holding an electron. The spin quantum number is the spin of an electron.
Do quantum numbers define the energy states and the orbitals available to an electron?
Yes, quantum numbers define the energy states and the orbitals available to an electron. The principal quantum number (n) determines the energy level or shell of an electron, the azimuthal quantum number (l) determines the shape or orbital type, the magnetic quantum number (m) determines the orientation of the orbital, and the spin quantum number (+1/2 or -1/2) determines the spin state of the electron. Together, these quantum numbers provide a complete description of the electron's state within an atom.
In many-electron atoms which quantum numbers specify the energy of an electron?
the quantum number n determines the energy of an electron in a hyrdogen atom.
What does the principal quantum number tell you?
The principal quantum number is the level of the most energetic electrons in an atom. It also corresponds to which period the element is in on the periodic table. For example, barium has a principal quantum number of 6 because its valence electrons are in level 6, and the element is in period 6.
What is the term used to label the energy level of electron?
Principal quantum numbers (n).
What is a principal quantam number?
The principal quantum number refers to the electron shell, or energy. Refer to the related link to read a Wikipedia article about quantum numbers.
What is the principal quantum number value for the highest energy electron in carbon atomic number 6?
The principal quantum number for the highest energy electron in carbon would be 2. It is easy to spot this, since carbon exists in row 2 of the period table. The row in which an element resides always shows the highest value of n, or the principal quantum number, that an electron can reside in.

What does the first quantum number (n) describe?
Which orbital is being occupied ^^^^ WRONG UPDATE 1/12/16: APEX ANSWER IS The energy level of the electron.

What information does the first quantum number of an electron give?
The energy level the electron is in
The amount of energy needed to move an electron from one energy level to another is an?
The amount of energy needed to move an electron from one energy level to another is called a quantum.
What is the definition of quantum number?
Four quantum numbers are used to describe electrons. The principle quantum number is the energy level of an electron. The angular momentum number is the shape of the orbital holding the electron. The magnetic quantum number is the position of an orbital holding an electron. The spin quantum number is the spin of an electron.
What part of the atom is able to be lost or gained?
the energy is require to remove an electron from an atom (ionization energy) but when electron is absorbed in an atom energy is released (electron affinity) however 2nd electron affinity is endothermic ,energy is require.
