The shape of $s$-orbital is

Explain the arrangement of orbitals in increasing order of energy on the basis of the $(n + l)$ rule.

If $n + l = 6$,then the total possible number of subshells would be

$2p$ orbitals have

The maximum number of unpaired electrons that can be present in $d$-orbitals is

Although no currently known element contains electrons in $g$ orbitals in the ground state,it is possible that such an element will be found or that electrons in excited states of known elements could be in $g$ orbitals. For $g$ orbitals,$l = 4$. What is the lowest value of $n$ for which $g$ orbitals could exist? What are the possible values of $m_l$? How many electrons could a set of $g$ orbitals hold?
