CHEM 112 Chapter Notes - Chapter 2: Covalent Bond, Manganese, Ionic Bonding
Document Summary
Chapter 2 notes - atoms, molecules and ions. Refer to the chemistry history timeline for this chapter. 2. 3 dalton"s atomic theory: atomic theory, each element is made up of tiny particles called atoms, the atoms of a given element are identical, chemical compounds are formed when atoms combine with each other. A given compound always has the same relative numbers and types of atoms: chemical reactions involve reorganizations of the atoms. The atoms themselves are not changed in a chemical reaction: avogadro"s hypothesis, at the same conditions of temperature and pressure, equal volumes of different gases contain the same number of particles. Element 109 = un (1) nil(0) enn(9) ium = unnilennium bi = 2 sept = 7 un = 1 hex = 6 tri = 3 oct = 8 quad = 4 enn = 9. 2. 8 naming simple compounds: ionic compounds, positive ion is always named first, negative ion second.
