Good question! Experiments show that the electron "behaves" as if it is a spinning ball of charge. But be careful...the electron IS NOT a spinning ball of charge. Instead the concept is quantum mechanical and has no actual classical analogy.
why we r taking the spin of the electorn is +1/2 or -1/2 is there any relation bet rotational symmetry

∙ 13y agoReally, this relates to Hunds Law, which states that within an Atomic Orbital, the electrons will spin parallel to one another. This is a fundamental characteristic of the subatomic particle, electrons.

∙ 11y agoThe spin quantum number, signified by the letter "s," is one of four quantum numbers that characterize the quantum state of an electron including a) the principal quantum number, b) teh azimuthal quantum number, c) the magnetic quantum number, adn the spin quantum number. The spin quantum number parameterizes the intrinsic angular momentum (spin angular momentum, or simply spin) of a given particle.
Paul Dirac's wave equation in 1930, which unlike Schrodinger's was relativistically invariant, predicted the magnetic moment, treated the electron as a point particle and provided a solution for all four quantum numbers, including the spin, "s."

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.
Who proposed spin quantum number?
Ullenbeck and Gowdsmith
Names and symbols of the four quantum numbers required to define the energy of electrons in atoms?
These are: principal quantum number (n), azimutal quantum number (ł), magnetic quantum number (m), spin quantum number (sd).
What is the definition of quantum number?

What is the set of quantum number for 4d orbital?
n (principle quantum number) = 4 l (angular momentum quantum number) = 2 ml (magnetic quantum number) = -2, -1, 0, 1, or 2 ms (spin quantum number) = +1/2 or -1/2

Which quantum number not include in defining orbit of a particle?
Spin.
What quantum number is a whole number?
The first three quantum numbers (principle, angular momentum, magnetic) are all whole numbers. The last quantum number (spin) is either ½ or -½.
What is the set of quantum number for 4d orbital?
n (principle quantum number) = 4 l (angular momentum quantum number) = 2 ml (magnetic quantum number) = -2, -1, 0, 1, or 2 ms (spin quantum number) = +1/2 or -1/2
What is a quantam state with zero spin?
A quantum state with zero spin is a state where the angular momentum of the system is zero. This means that the system has no intrinsic angular momentum or spin. In other words, it has a spin quantum number of 0.
What does a quantum number describe?
n is the first quantum number. It is the principle quantum number. It refers to what energy level it is and will be one greater than the number of nodes in the orbital. l is the second quantum number. It is the angular momentum quantum number and refers to the shape of the orbital. ml is the third quantum number. It is the magnetic quantum number and it refers to the orientation of the orbital. ms is the fourth quantum number. It is the spin quantum number and refers to the magnetic character of the orbital.
