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.

In NaCl, there exists Na+ and Cl- ions and with the electron configuration of [He]2s22p6 (for Na+) and [Ne]3s23p6 (for Cl-)
The electron dot configuration for calcium is written as Ca•. This represents the calcium atom with two electrons in its outermost shell.
Na. (sodium with one dot, representing one valence electron)
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 diagram for Fr (Francium) would consist of one dot to represent its single valence electron. This electron is located in the outermost energy level of the atom.
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 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.
Go to NASIOC dot com and ask there. The answer awaits.
Red dot sights are unique in part to their reflection configuration. Unlike many other sights, red dot sights are non-magnifying reflectors which, as the name implies, means the sight provides no magnification.
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.
