Valence electrons.
Each dot represents one valence electron.
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 Lewis structure is a model that uses electron-dot structures to show how electrons are arranged in molecules. Pairs of dots or lines represent bonding pairs this is a CO32− model
the dots are the number of electrons in an elements valance shell (last shell). if it has no dots, it means it has lended its electrons to another element to become stable like its nearest noble gas.
the Lewis structure of B or Boron would have three small dots posing as electrons. These dots can be placed anywhere around the B symbol.
6 Dots
The three dots around Al's Lewis structure represent Al's unpaired valence electrons.
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.

The Lewis structure of fluorine contains 9 electrons, which 7 of them are valence. This means the letter F will be in the middle with 7 dots surrounded it, which would represent the 7 valence electrons.
