- We are looking at defining the terms chemical formula, chemical symbol, and chemical equation. A chemical symbol is really another name for an atomic symbol found on the periodic table. It is the one or two letter designation for each atom found on the periodic table. An example would be Na for sodium.

Chemical formula A chemical formula identifies each constituent element by its chemical symbol and indicates the proportionate number of atoms of each element. In empirical formulas, these proportions begin with a key element and then assign numbers of atoms of the other elements in the compound, as ratios to the key element. chemical formula is not a chemical name, and it contains no words. Although a chemical formula may imply certain simple chemical structures, it is not the same as a full chemical structural formula.

Questions and Answers The number and arrangement of electrons in an atom define the chemical characteristics of elements. One way to think of electrons is that they are the part of the atom that shows. They are the outer coating. They are the glue that holds atoms together in chemical bonds. The basic electron number is determined by the number of protons. In a stable carbon-12 atom there are six electrons, since there are six protons.

Chemical formula A chemical formula is a way of expressing information about the proportions of atoms that constitute a particular chemical compound, using a single line of chemical element symbols, numbers, and sometimes also other symbols, such as parentheses, dashes, brackets, commas and plus (+) and minus (−) signs.tructural formula for butane. This is not a chemical formula. Examples of chemical formulas for butane are the empirical formula C 2 H 5, the molecular formula C 4 H 10 and the condensed (or semi-structural) formula CH 3 CH 2 CH 2 CH 3.

Chemical Laboratory Equipment Shapes and Usage A chemical test is a qualitative or quantitative procedure designed to prove the existence of, or to quantify, a chemical compound or chemical group with the aid of a specific reagent. The chemical laboratory equipment diagrams use special shapes to represent different types of chemical tester. It's easy to design chemical test with these pre-defined lab equipment shapes for students and teachers. All shapes are vector and can be grouped, ungrouped and recolored.

Chemical Symbol: Definition & Examples A chemical symbol is a short-hand method of representing an element. Instead of writing out the name of an element, we represent an element name with one or two letters. As you know, the periodic table is a chemist's easy reference guide.n this lesson, you will learn that a chemical symbol is a short-hand way to represent an element and each element on the periodic table has a unique chemical symbol. You'll become familiar with identifying some common elements by their chemical symbol.
