Some examples are as follows, $$ \ce{[Na]+ [Cl]-} \, , \\ \ce{[Mg]^2+ 2[Cl]-} \, , \\ \ce{3[Mg]^2+ 2[N]^3-} \, . $$ Hopefully you get the idea, so a general rule is: $$ \text{#ions}[\text{element symbol}]^{\text{magnitude of cation charge}} \text{#ions}[\text{element symbol}]^{\text{magnitude of anion charge}} \, . $$

1$\begingroup$ I appreciate your answer but my concern is how to represent in 3D model. Let's say Sodium acetate,the ionic bond between Na+ and O- .You may refer jmol for 3D models. $\endgroup$ Commented Jul 15, 2015 at 4:23

Concerning the depiction of ionic bonds, the Graphical Representation Standards for Chemical Structure Diagrams (IUPAC Recommendations 2008) read as follows:
Structures that are known to be ionic should be depicted as such. They should be drawn with atoms bearing explicit positive and negative charges, and there should be a space (rather than a bond) between those atoms.

$\begingroup$ I think you should expand the quote to include some points from the next section "GR-7.2 Positioning of components" as well, namely: 1) that there are two ways to position components and 2) what is the recommended way of drawing salts with more than two components. $\endgroup$– WildcatCommented Jul 14, 2015 at 9:39
