Sodium chloride has an ionic bond and form large lattices.
The electron dot configuration of Al is 3 dots, arranged as 2 dots on one side and 1 dot on the other. For S, the electron dot configuration is 6 dots, distributed on all four sides of the symbol.

Na. (sodium with one dot, representing one valence electron)
In NaCl, there exists Na+ and Cl- ions and with the electron configuration of [He]2s22p6 (for Na+) and [Ne]3s23p6 (for Cl-)
The given electron configuration corresponds to a total of 34 electrons. In an electron dot structure, only the valence electrons are represented. For the configuration 4s² 3d¹⁰ 4p⁴, the valence electrons are 6 (2 from 4s and 4 from 4p). Therefore, the electron dot structure would have 6 dots.
Calcium has two valence electrons, both of which are unpaired. •Ca•
to find the electron dot configuration of an element simply draw dots, symbolizing valance electrons, in a way that they are farthest from each other around the symbol of the element you are using.
The Lewis dot structure for NaCl shows Na with one valence electron donating to Cl, which has 7 valence electrons. The resulting structure has Na surrounded by 8 electrons (full octet) and Cl surrounded by 8 electrons (full octet).
The electron configuration of Fr, or Francium starts with the base configuration of [Rn]. The outer shell is 7s1, giving 1 valence electron.
The dot structure of NaCl, sodium chloride, would show sodium as Na with one electron being transferred to chlorine, Cl, resulting in Na+ and Cl- ions being attracted to each other due to their opposite charges. This forms an ionic bond between sodium and chlorine.
In the Lewis dot structure for NaCl showing an ionic bond, sodium (Na) will have one dot representing its single valence electron, and chlorine (Cl) will have seven dots, one for each of its seven valence electrons. The electrons will be shown transferring from sodium to chlorine to form an ionic bond, with sodium losing its electron to become a cation (Na+) and chlorine gaining an electron to become an anion (Cl-).
The Lewis dot symbol of bromine (Br) is represented by the symbol "Br" surrounded by seven dots, with two dots on three sides and one dot on one side. This configuration shows that bromine has seven valence electrons.
