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.

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.
Shapes of electorn orbitals are determined by?
By azimuthal quantum numbers.
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 is the maximum number of s orbitals p orbitals d orbitals and f orbitals in any single energy level in an atom?
For fun, let's give them numbers instead of letters, and call s "0", p "1", d "2", and f "3".Then the number of distinct orbitals for any given principal quantum number (which is a more precise way of the concept you meant when you said "energy level") is twice the number plus 1... though the principal quantum number must be higher than the numbers we just gave the orbitals in order for there to be any at all (there aren't any 1p orbitals, for example). For principal quantum number of at least four, there are 1 s orbital, 3 p orbitals, 5 d orbitals, and 7 f orbitals. If we call the four quantum numbers n, l, m, and s, where n is the principal quantum number, l is the azimuthal quantum number, m is the magnetic quantum number, and s is the spin quantum number, the permissible values are: n - any integer such that 0 < n ("shell") l - any integer such that 0 <= l < n (orbital "type" - s, p ,d ,f, g, h, i, etc.) m - any integer such that -l <= m <= l (individual orbitals of type l) s - -1/2 or +1/2 (electron "spin")
Can two electron have the same set of quantum number?
Pauli's exclusion principle

Shapes of electorn orbitals are determined by?
By azimuthal quantum numbers.
All of the orbitals in a given electron shell have the same value of the?
Principal quantum number.
What do quantum numbers of electrons represent?
The energy levels and orbitals the electrons are in
What is the definition for Quantum mechanical model?
it is a model that uses complex shapes of orbitals (electron clouds).
Which set of quantum numbers cannot occur together to specify an orbital?
Quantum numbers specify the orbitals in an atom. The set of numbers that cannot occur is n=3,I=3, m(sub)I=2 because there are no F-orbitals.
What is electron configuration mnemonic device?
also known as the diagonal rule device. Chemist use the principle and angular momentum quantum numbers to compare to the relative energy of the orbitals.

How are quantum numbers different from an address?
The four quantum numbers, n, l, m1, and ms, are all solutions to Schrödinger's equation. These numbers are used to assign each electron in an atom an "address." They "uniquely characterize an electron and its state in an atom" ("Quantum Number").
