What are the significances of quantum number l and ml? Designate the two orbitals having n==1,l=0 and n=3,l=2. respectively. Explain- there is no existence of 2d orbital.

Explain why there is no existence of 2d orbital.

Designate the orbitals bearing quantum numbers. n=2,l=1 n=3,l=2

designate the quantum number indicated by the following orbitals. 2s,3d,4p,4f.

The electron , identified by quantum numbers n and l (i) n=4, l=1 (ii) n=4, l=0 (iii) n=3, l=2 (iv) n=3, l=1, can be placed in order to highest, as

What is orbital? Draw the shapes of 2p and 3d orbitals.

If the value of principle quantum number(n) is 3, what are value of azimuthal quantum number(l)?

The length between two bridges of a sonometer wire is L, tension is T and the fundamental frequency is N, if the length between the bridges and tension both are doubled, explain if there is any change in fundamental frequency.
