However many valence electrons there are, which I believe is 3
Ga with three dots around it. Ga 2/8/18/3

The electron-dot structure for HBr would be:H:Br: (with two more pairs of dots on the top and bottom of Br)
The number of valence electrons in the atom.
The dot structure for I will have have 7 dots around it. This will consist of 3 lone pairs, and then 1 single electron.
The monomer GaI3 has the Lewis dot structure:- .. : I : .. .. .. : I : Ga : I : .. .. The dimer has 2IGaI2GaI2 has bridging iodine atoms and each Gallium achieves a full octet by sharing of a lone pair on the one of the bridging iodine atoms.
The electrons in the valence shell are shown in the Lewis structure of an atom by dots. Additionally, if it contains bonds, they are shown by dashes.

5 dots around AS.

Two dots are shown in the electron dot diagram for calcium in group 2 and period 4 with 20 protons and 20 electrons.

Valence electrons.
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 electron-dot representation of a carbon atom show only four dots because the dots represent only the valence electrons (the ones placed in the outermost shell). The carbon atom has four electrons in it's outermost shell. !
