As mentioned in the previous section titled A Short History of Chemistry, many scientists identified elements, determined their characteristics, similarities, and differences, and designed symbols for them. Using unique experiments, scientists devised ways to define the structure of atoms and determine atomic weights, sizes, and electrical charges as well as energy levels for atoms. 

Symbol for quantum yield. 2. Symbol for one of the space coordinates in the three-dimensional, spherical polar coordination system. 3. Symbol for electric potential. 4. Symbol for volume fraction. 5. With a subscript designation, symbol for a Dalziel coefficient. 6. Symbol for fugacity coefficient. 7. Symbol for osmotic coefficient. 8. Symbol for heat flow rate. 

In conducting an F-test for this situation, Sf is assigned as the greater expected variance. The null hypothesis, H,). that there is no difference in variance and the alternative hypothesis. H>, that Sf is larger than sl. are designated symbolically as... 

Describe the general characteristics of the first (low-est-energy) hydrogen atomic orbital. How is this orbital designated symbolically Does this orbital have a sharp "edge" Does the orbital represent a surface upon which the electron travels at all times ... 

Figure 1.3 shows a spectrum of 3,4-dimethyl-5-hexen-3-ol for which the group frequencies have been designated. Symbols used are v, stretch 5, asymmetric bend 5, symmetric bend /S, in-plane bend y, out-of-plane bend (Szymanski, 1966).

Rapid comprehension of symbols within the vehicle can be even more critical than comprehension of road signs because extracting that information also involves moving the eyes away from the road. Thus, slow comprehension of and long fixations on in-vehicle symbols can contribute to driver distraction (see Chapter 13). To minimize that possibility it is important to design symbols that meet the ergonomic principles stated above, and then assess not only the comprehension of the symbols but also the time needed to respond to them.
