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
Really, 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.
The 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."

Names and symbols of the four quantum numbers required to define the energy of electrons in atoms?
The four quantum numbers are: Principal quantum number (n) - symbolized as "n" Azimuthal quantum number (l) - symbolized as "l" Magnetic quantum number (ml) - symbolized as "ml" Spin quantum number (ms) - symbolized as "ms"
How many quantum numbers are there in quantum theory?
There are four quantum numbers: principal quantum number (n), azimuthal quantum number (l), magnetic quantum number (m_l), and spin quantum number (m_s). These numbers describe different properties of an electron in an atom, such as energy level, shape of the orbital, orientation in space, and spin.
Who proposed spin quantum number?
The concept of the spin quantum number was proposed by George Uhlenbeck and Samuel Goudsmit in 1925 to explain the behavior of electrons in an external magnetic field. Spin is a quantum property that describes the intrinsic angular momentum of particles.
What is the set of quantum number for 4d orbital?
The quantum numbers for the 4d orbital are n=4, l=2, ml=-2, -1, 0, 1, 2, and ms=+1/2 or -1/2. The principal quantum number (n) represents the energy level, the azimuthal quantum number (l) represents the subshell, the magnetic quantum number (ml) represents the orientation of the orbital, and the spin quantum number (ms) represents the spin of the electron.
How many possible values are there for the spin quantum number?
The spin quantum number can have two possible values: +1/2 or -1/2.
What could the fourth quantum number of a 2s2 electron be?
ms= +1/2

How many quantum number are required to specify a single atomic orbital?
Four quantum numbers are required to completely specify a single atomic orbital: principal quantum number (n), azimuthal quantum number (l), magnetic quantum number (m), and spin quantum number (s). These numbers describe the size, shape, orientation, and spin of the atomic orbital, respectively.

What is the quantum number for helium?
There are several different quantum numbers for a given atom (principle quantum number, the angular quantum number, the magnetic quantum number, the spin quantum number, etc) .I assume you are looking for the Principle Quantum number, n, which is equal to the row (period) in the period table in which the element is situated.For helium, the principle quantum number is 1.i.e. n = 1As another example; the principle quantum number for potassium (K), n = 4.
