Explain about (i)Magnetic quantum number (ii)Spin number (iii)Magnetic quantum number] |
|
Answer» SOLUTION :(i) Magnetic quantum number ltbtgt(1)It is DENOTED by the letter `(m_l)`, it takes integral value ranging from -l to +l through 0. (2) Different values of m 8for a given l value,represent different orientation of orbitals in space. (3)The Zeeman Effect (the splitting of spectral LINES in a magnetic field)provides the ex[ermimental justification for this qutanum number. (4)The magnitude o the angular momentum is determined by the quantum numbr l while its direction 8is given by magnetic quantum number. (ii) Spin quantnum number (1)The spin quantum number represents the spin of the ELECTRON and is denoted by the letter `(1m_s)`. (2)The electron in an atom revolves not only around the nucleus but spins.It is USUAL to twite this as electron spins about its own axis either in a clockwise direction or in anti-clockwise dr=irection. (3) Correspondin g to the clockwise and anti-clockwise spinning of the electorn,maximum two values of `(m_s)` is eqaul to `-1//2 and +1//2.` |
