Study Notes

Matter and States of Matter

  • Matter is anything with mass and volume
  • Four states of matter: solids, liquids, gases, and plasma
  • Plasma is superheated matter, with electrons stripped from atoms, forming an ionized gas
  • Bose-Einstein condensate (BEC) is a fifth state, where atoms or particles are near absolute zero
  • Superfluidity is frictionless fluid flow

Weight and Mass

  • Weight is the force of gravity on an object's mass
  • Weight = Mass x Gravity

Atomic Structure

  • Electrons are negatively charged particles
  • Atomic number is the number of protons in an atom's nucleus
  • Electron capacity is the maximum number of electrons in a shell or sub-shell (2n²)
  • Valence is the number of chemical bonds an atom can form
  • Ionization is the process of an atom gaining or losing electrons, creating cations (loss) or anions (gain)

Electrical Conductors

  • Conductors allow easy current flow; good examples include gold, copper, silver
  • Insulators do not conduct current well (e.g., glass, ceramic, plastic)
