Question

Draw the electronic distribution for fluorine ($\mathrm{Z}=9$)

Answer 1

1. Atomic number of fluorine ($\mathrm{F}$), $\mathrm{Z}=9$
2. Therefore there are $9$ electrons and electronic arrangement is : $$\begin{gathered} \mathrm{K}\mathrm{M} \\ 27 \end{gathered}$$
3. Electronic configuration maybe written as $2,7$
