For fluorine: 8 dots.
In the Lewis dot structure for a fluorine atom, there should be 1 bond displayed, as fluorine has 1 unpaired electron that can form a single bond with another atom.

The Lewis structure for Helium is He with two dots next to each other, above the He symbol. The dots must be drawn next to each other, they represent the two electrons found in the 1s-orbital of the Helium atom.
A semi-condensed formula is a shorthand way of representing a molecule's structure where covalent bonds are shown but not all atoms or bonds are explicitly drawn. It strikes a balance between a fully condensed formula (where only bonds between atoms are shown) and a structural formula (where all atoms and bonds are depicted).
