  • What is ionization?
    The process by which atoms lose or gain electrons.
  • What do you say when an atom has gained or lost electrons?
    that it has been ionized
  • What do pure substances consist of?
    just one type of matter
  • what is an anion or negetive ion?
    An atom that gains electrons and acquires a net negetive charge
  • What does "cluster" mean?
    group of the same type of things that are close together
  • What are some elements that large clusters occur in?
    They can occur in metals, diamonds, and graphite.
  • What are some ways in which atoms can ionise?
    friction, electric discharges, collisions with other particles, or at extremely high temperatures that occur inisde stars
  • What is a cation or a positive ion?
    An atom that loses electrons and aquires a net positive charge
  • What do mixtures consist of?
    two or more pure substances
  • What are the 3 forms in which elements can occur?
    Isolated atoms, large clusters, or molecules
  • Which particles can transfer between atoms?
    electrons. Protons and neutrins are fixed in place in the nucleus.
  • What boes it mean to "bond" something?
    To join two things strongly together

    Elements or compounds
