Chapter AS, Problem 29PQ

Interpretation Introduction

Interpretation:

The shape of the orbital of 2p electrons has to be determined.

Concept Introduction:

Orbital define the region in space where there is possibility to find electron. It is function of principal quantum number $\left(n\right)$, angular momentum quantum number $\left(l\right)$, magnetic quantum number $\left(m\right)$.

$n$ indicates energy and distance from nucleus and represents the shell. Its allowed values are all positive whole numbers.

$l$ indicates shape of orbital. Its allowed values are all positive integer from 0 to $n-1$. The table for the $l$ values is as follows:

  $\begin{array}{cccccccc}l& 0& 1& 2& 3& 4& 5& 6\\ \text{Subshell}& s& p& d& f& g& h& i\end{array}$

$m$ indicates the arrangement of orbitals. The values of $m$ for any orbital is given by any integer value from $-l$ to $l$.
