Chlorine is a group 7 element and has 7 valence electrons. When calcium loses its two valence electrons to become an ion, the Lewis structure shows it with no dots (electrons). The Ca and Cls are near each other but the two dots from each Cl should not be interpreted as a covalent bond.
Richard Lewis is a linguist who speaks ten languages and who has journeyed far. In his travels he has found he can segment national cultures into three approximate categories (although he also warns of stereotyping).

Lewis Structures: The Basics. In a nutshell, a Lewis structure is a pictorial representation of the atomic structure and electron configuration of an atom or a compound. Single atoms are represented by their unique chemical symbol, electrons are represented as single dots, and shared pairs of electrons are represented by a single dash (−) for a single pair, a double bar (=) for a double pair, and a triple bar (≡) for a triple pair.
Jul 08, 2013 · A simple procedure for writing Lewis dot structures was given in a previous post entitled “Lewis Structures and the Octet Rule”. Several worked examples relevant to this procedure were given in previous posts please see the Sitemap - Table of Contents (Lewis Electron Dot Structures).
*Put 1 dot (to represent 1 electron) on each side before adding a second dot to that side of the box – Pauli’s Exclusion Principle So the final product looks like this: Al Lewis Dot StructureA model that uses electron-dot structures to show how electrons are arranged in molecules.
The structures of molecules that are held together by covalent bonds can be diagrammed by Lewis electron -dot structures. The hydrogen molecule is shown in Figure below. On the left is a single hydrogen atom with one electron. On the right is an H 2 molecule showing the electron cloud overlap.
Nov 02, 2012 · CHCl3 is called chloroform. First we need to count the total number of valence electrons. We just add the valence electrons of each atoms involved.

Thus, for Cl 2 CO, each chlorine needs a single bond and oxygen needs two bonds; the Lewis dot structure would be (Cl:) 2 C::O. Note that a single bond needs a pair of electrons (one group), a double bond needs two pairs (also one group), and a triple bond needs three pairs (still just one group, since it points in one direction only).
