The study of chemistry is rich in historical development. The learning standards encourage the inclusion not only of important concepts but also of the scientists who were responsible for discovering them. Robert Boyle, generally regarded as one of the fathers of modern chemistry, introduced systematic experimental methods into the study of chemistry. John Dalton laid down the
tenets of the atomic theory at the beginning of the 19th century. By mid-century Mendeleev had completed most of his work organizing the Periodic Table, and Amedeo Avogadro had provided keen insights into the relationships of gaseous
molecules. Ernest Rutherford discovered the nucleus, and soon afterward Henry Moseley identified the atomic number as the identifying factor of the elements. Soon after, Albert Einstein proposed the insight into the interrelationship of
matter and energy. Marie Curie worked with radioactive substances showing natural transmutations. Linus Pauling provided insights into the nature of the chemical bond in the 1930s, and introduced electronegativity values, an important tool in understanding
bonding. -excerpt from the Physical Science Chemistry NYS Curriculum
