# What is the electron configuration of fluorine?

$1 s 2$ $2 s 2$ $2 p 5$
The first 2 columns, IA and 2A, are your 's' orbitals. As you move across the table you move to different orbitals, $s$, $p$ and $d$.
$s$ orbitals are contained in the first 2 columns.
$p$ orbitals are IIIA and VIIA orbitals.
$d$ orbitals are transition metals.
