For complete description of an electron in an atom ,the number of quantum numbers required is (A) One
(B) Two
(C) Three
(D) Four

For the valency electron in copper, the four quantum numbers are

For a one-electron atom, the set of allowed quantum number is -

Number of two electron can have the same values of … quantum numbers

The complete designation of the electrons in an atom is given with the help of four quantum numbers. They specify the shell, sub-shell and the orbital in a which a particular electron can be present. (i) Which quantum number describes the electron spin ? (ii) What is the significance of this quantum number ? (iii) If the two electrons repel each other and will not be in a position to remain in the same orbital.

No two electrons in an atom will have all the four quantum numbers same. This statement is known as

The statement ''No two electrons in an atom can have all the four quantum numbers identical'' is known as the....
