Which of the following statements about quantum numbers are TRUE ?
1)They describe the number of protons and neutrons in an atom.
2)ml and ms are quantum numbers.
3) One quantum number can fully describe an atomic orbital.
4) It takes three quantum numbers to specify an atomic orbital.
5)They describe the energies of electrons in an atom.
A total of four quantum numbers are there to describe completely the movement of an electron within an atom. The combination of all four quantum numbers of electrons in an atom is described by means of the wave function by the Schrödinger equation. Each electron in an atom has its own set of quantum numbers. Quantum numbers are important because they can be used to determine the electron configuration of an atom and the probable the location of electrons in an atom. Quantum numbers are also used to understand the characterization of the ionization energy and the atomic radius of atoms.
The four quantum numbers are:
The principal quantum number (n),
The orbital angular momentum quantum number (l),
The magnetic quantum number (ml), and
The electrons spin quantum number (ms).
Given : The following statements about quantum numbers are TRUE.
1) They describe the number of protons and neutrons in an atom: False
May be used to describe to describe the nucleons (protons and neutrons), but commonly describes the electrons in an atom.
2) ml and ms are quantum numbers : True
ml is the magnetic quantum number describes the number of orbitals and orientation within the subshell and ms is the spin quantum number, describes the direction of the electron spin.
3) One quantum number can fully describe an atomic orbital: False
The three coordinates that is from Schrodinger wave equation i.e., the principle, the angular and the magnetic quantum number are enough to describe the atomic orbital.
4) It takes three quantum nu...
