Unformatted text preview: Chemistry Basics Atom = basic building block of matter Nucleus contains protons and neutrons Protons are + charged and massive. Atomic number = # of protons in nucleus Neutrons have no charge and are slightly more massive than protons Atomic mass number = sum of protons and neutrons in the nucleus Isotopes are atoms of the same element with different atomic masses. 14 C, 18 O Electrons orbit the nucleus at a relatively great distance, have a very small mass and a - charge. The number of electrons = atomic number in neutral atoms. Ions are atoms with an electrical charge. Atoms that lose electrons become positive ions Atoms that gain electrons become negative ions Universal solvent (Like dissolves like) All three physical states occur in a narrow temp range. Solid is lower density than liquid High surface tension and cohesion with other substances Extremely high specific heat and heat of vaporization Specific heat = 1.00 calorie / g o C Heat of vaporization = 540 cal. / g o C Heat of Fusion = 80.0 cal / g o C Solvent = most abundant substance...
