Science - Atoms in Reactions

  1. Explain the Law of Conservation of Mass
    This states that the total mass of reactants in a chemical reaction always equals the total mass of the products
  2. What is ionic bonding?
    This is a force of attraction between oppositely charged ions

    It occurs when one atom loses electrons and another atom gains these electrons

    If an atom gains an electron the ion is negative

    If an atom loses an electron the ion is positive
  3. If an atom gains an electron does the ion become positive or negative?
    Negative
  4. If an atom loses an electron does the ion become positive or negative?
    Positive
  5. What is covalent bonding?
    This is formed when pairs of electrons are shared between two atoms
  6. List the properties of ionic substances
    Usually solids

    Have high melting and boiling points

    Conduct electricity
  7. List the properties of covalent substances
    Usually liquid or gases

    Have low melting and boiling points

    Do not conduct electricity
