Unformatted text preview: Chapter 3: Molecules, Compounds and Chemical Equations Chemistry is centered around a new language- the language made out of periodic table of elements. Just as you first learn English alphabet to learn the English language, you must first learn the periodic table of elements to learn chemistry. Each entry in the periodic table is identified by a chemical symbol and is characterized by atomic number (which identifies the number of protons in the nucleus of that atom).
