STRUCTURE OF ATOM

Quantum numbers

principal quantum number:

• denoted by n

• n=1,2,3,4.......

• also represented by K,L,N,M....

• tells us the size and energy of the orbital.

Azimuthal quantum number:

• denoted by l

• takes values from o to n-1

• l= 0, 1, 2, 3,........n-1

• shape of the sub shell

Magnetic quantum number:

• represented by m_l

• takes values from -l to +l

• total (2l+1) m_l values exists.

• orientation of the orbital in the space.

Spin quantum number:

• represented by m_s

• values +1/2 and -1/2

• clockwise and anti clockwise rotation

•
