Question

What is the electron configuration of fluorine?

Answer 1

`1s2` `2s2` `2p5`

Explanation:

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.
