Write n, l and `m_1` values for 3s

An electron is present in '3p' subshell. Write the possible values for quantum numbers l and m.

Calculate n, l, m and s for 4f and 3d electrons.

An electron is in 4f orbital. What possible values for quantum number n, l and m _(l) can it have,

Give all possible values of l, m _(l) and m _(s) for electrons when n =3.

Let L_(1),L_(2),L_(3) be three straight lines a plane and n be the number of circles touching all the lines . Find the value of n.

Calculate n, l, m and s for 4f and 2p electrons.
