Shell Subshell

The rule used to determine the maximum number of electrons in a subshell of an atom is:

1.	4l+2	2.	2l+1
3.	4l-2	4.	2n2

A pair of d-orbitals having electron density along the axes is:

1. $d_{z^2},$ $d_{xz}$

2. $d_{xz},$ $d_{zy}$

3. $d_{z^2},$ $d_{x^2-y^2}$

4. $d_{xy},$ $d_{x^2-y^2}$

The relation between ( = number of permissible values of magnetic quantum number (m_l) for a given value of azimuthal quantum number (l) is:

1.		2.
3.		4.
