Symbol list

Using an element identity key provided by your teacher, convert the unknown element letters (A through R) used in Data Table 2 to their actual chemical symbols. List your arrangement of the actual chemical identities in Data Table 3. Compare the arrangement of elements in Data Table 3 with an actual periodic table. How accurately does your periodic table match the actual periodic table Complete Data Table 4. 

In addition to the polyhedra symbols listed in Fig. 2.2, further symbols can be con-... 

Figure 4-1 gives the symbols that should be used. If the equipment is not given in the symbol list, it is drawn to look like itself. 

An internationally accepted chemical notation makes use of symbols to represent elements and compounds, and advises on naming chemical compounds. In this notation, the elements are represented by one or two letters, many of which are drawn from the elements Latin or Greek names. The number of atoms of an element in a molecule is represented by a subscript written after the symbol thus Au (the first two letters of aurum, the Latin name for gold) represents an atom of gold Cu (the first two letters of cuprum, the Latin name for copper), an atom of copper and C (the first letter of carbon), an atom of carbon O represents an atom of oxygen and 02, a molecule of oxygen. The symbols listed below provide examples of the presently accepted form of chemical notation ... 

The last column of the following table of symbols lists either the equation or equations (Arabic numbers in parentheses) or the section (Roman numerals) in which the symbol is introduced and defined. 

In the list of equations of state and of some other equations used in detonation calculations, which follows, the symbols listed by Cook (Ref 12, pp 376-78) will be used, with a few exceptions. Small v will be used for specific volume (cc per gram of expl) and small e for specific energy, although some investigators use caps. For pressure which does not include intrinsic pressure, tu, small p will be used, while P will be used for total pressure p + tu (See eq 6) and not for p/p2 listed by Cook. Some of the symbols used in equations of state are not listed by Cook... 

Pick a number, and you can make a list of integers that are multiples of that number. You can also make a symbolic list (using math symbols) of integers that are multiples of a number by starting with n and adding the number repeatedly. For example, a list of six consecutive multiples of 7, starting with 63 is 63, 70, 77, 84, 91, 98. Symbolically, a list of any six multiples of 7 is n, n + 7, n + 14, n + 21, n + 28, n + 35.

The symbols listed below are used throughout this chapter. In most cases, the usage follows the recommendations of the IUPAC Commission on Electrochemistry [8] however, there are exceptions. 

There are eight symbols listed below with their meanings. It is important to become familiar with them before proceeding further. 

All acronyms used here are included in the Abbreviations and Symbols list following the Preface. 

You will need the periodic table and the element/symbol list to answer the following questions about positive ions. 

The symbols listed here are internationally agreed and should not be changed in other languages or scripts. See sections 1.3 and 1.4 on the printing of symbols for units. Recommended representations for these symbols for use in systems with limited character sets can be found in [7]. 

The further symbols listed in the table below are also to be found in the literature, but their use is to be deprecated. Note that the names and symbols for 10"9 and 10 12 in this table are based on the American system of names. In other parts of the world a billion sometimes stands for 1012 and a trillion for 1018. Note also that the symbol ppt is sometimes used for part per thousand, and sometimes for part per trillion. 

Helmholtz energy. The subscripts m and a refer to "per mole" and "per unit area", respectively. Hence, in SI units is in J mol and in J m". Changes in functions are indicated by a A, with a subscript indicating the nature of the change. Thus. Ajj F is the change in Helmholtz energy upon adsorption. See further sec. 9a for nomenclature and lUPAC recommendations and the symbol list at the beginning of this book.
