Clues

  • A drawing to show the arrangement of the outer shell electrons only of the atoms or ions in a substance. (3, 3, 5, 7)
  • A graph will show this if the line of best fit is a straight line through the origin. (8, 12)
  • A measure of the work done or energy transferred to the lamp by each coulomb of charge that passes through it. The unit of potential difference is the volt (V). (9, 10)
  • A set of numbers to show the arrangement of electrons in their shells (or energy levels) e.g. the electronic structure of a potassium atom is 2,8,8,1. (10, 9)
  • Bonding electron that is no longer associated with any one particular atom. (11, 8)
  • Breaking down food using oxygen to release energy for the cells. (7, 11)
  • Polymer that can form extensive cross-linking between chains, resulting in rigid materials which are heat-resistant. (13, 7)
  • The attraction between the individual molecules in a covalently bonded substance. (14, 5)
  • The average mass of an element compared with carbon-12 (which is given a mass of exactly 12). The average must take into account the proportions of the naturally occurring isotopes of the element. (8, 6, 4, 2)
  • The variable for which values are changed or selected by the investigator. (8, 11)
