Question

Draw the electron dot structure of Sodium chloride $$[Na = 11, \ Cl = 17]$$


Solution



Sodium chloride

$$\begin{matrix} Na (11) \Rightarrow  & 2 & 8 & 1 \\ & K & L & M\end{matrix}$$
$$\begin{matrix} Cl (17) \Rightarrow  & 2 & 8 & 7 \\ & K & L & M\end{matrix}$$

Sodium loses one electron to chlorine forming a positive ion and chlorine gains one electron forming a negative ion. These ions form an electrovalent bond and are held strongly by electrostatic forces of attraction.
