  • How can you prove that an element is truly an element (not a molecule)?
    It can't be broken down into anything smaller.
  • What do we call the central core of an atom?
    the nucleus
  • If atoms are mostly empty space, why can't I push my hand through my desk?
    Atoms appear solid because of the rapid movement of the electrons.
  • What element is diamond made of?
    carbon
  • An ______________ is a substance that can't be broken apart into other substances.
    element
  • How many atoms must join together to form a molecule?
    two or more
  • What is the result of an atom always having an equal number of protons and electrons?
    The atom has a neutral charge.
  • Carbon protons? Electrons? Neutrons?
    6 protons/6 electrons/6, 7, or 8 neutrons
  • What two elements make salt?
    sodium and chlorine
  • Electrons charge? Mass? Location? Speed?
    negative charge/small mass/travel rapidly around the nucleus
  • What makes up most of an atom’s mass?
    the nucleus
  • Which one is not a molecule? O/O2/H2O/NaCl
    O - because it is just one atom of oxygen - the others are 2 or 3 atoms combined

    color/hardness/density
  • What are the tiny particles that make up an atom?
    protons/electrons/neutrons
  • What is an atoms mostly made up of?
    empty space
  • How many atoms make up a molecule of water?
    3 - two hydrogen and one oxygen
  • How can carbon make so many different things with different properties?
    The answer lies in the way the atoms are arranged.
  • Identify the 4 forms of carbon.
    coal/graphite/diamond/buckyball
  • Which one is an element? water/salt/sodium/H20
    sodium
