explain the significance of the four quantum numbers associated with an electron
Answers
Answer:
Quantum numbers are important because they can be used to determine the electron configuration of an atom and the probable location of the atom's electrons. Quantum numbers are also used to understand other characteristics of atoms, such as ionization energy and the atomic radius.
Answer:
Quantum numbers are the numbers which define the location of electrons in the orbitals around the nucleus of an atom.
There are four quantum numbers, viz,
Principal quantum number (n) : It defines the main shell to which an electron belongs. The values of n =1,2,3,4,........
Azimuthal quantum number () : It tells us the number of subshells present in the main shell and the orbital to which an electron belongs. Its value is equal to 0 to (n-1).
Magnetic quantum number (m) : It informs the level of degeneracy of the orbitals. Its value is equal to -,0,+.
Spin quatum number (s) : It tells us whether the electron in an orbital is spinning in upward direction or downward direction. s has two values +1/2 for upward spin and -1/2 for downward spin.
