Question

Bonjour .-^-^

Explain three points about spin quantum no.

Thanks

Answer 1

Hey sisy...^_^

Here's. ur ans.

============

Spin Quantum Numbers ⬇

✡ It is represented by 's'

✡It gives information about electron spin or rotation of electrons in its own axis .

✡Spin is clockwise or anticlockwise . Clockwise direction is represented by +1/2 and anticlockwise by -1/2.

✡Spin quantum no. also represents angular momentum (spin angular momentum )

✌Hope it helps

Answer 2

1, It was proposed by Uhlenbeck and Goud smith

2, It is to explain possibility of doublets , triplets of a spectral line

3, Electrons not only revolves around nucleus bt also rotates around its own axis

4, Every electron has two possible states
¡) clockwise spin
¡¡) anti clockwise spin

The clockwise direction spin is represented by +1/2 and anticlockwise spin is represented by -1/2.

Hope it helps!!!
