... , electronegativity measures the tendency of bonded atoms to attract electrons. Linus Pauling invented this trend, based on a scale of zero to four. Elements are divided into families depending on their physical and chemical properties. These families are grouped on the periodic table according to horizontal rows with preceding roman numerals. The first family contains only one element, hydrogen. Because hydrogen, the ... compounds, chemists use a system called nomenclature to assist in forming precise, informative names that can be universally analyzed. The current system invented by th...
