  5. Bohr-Rutherford diagram.
    A model of the atom in which a central positive nucleus is surrounded by electrons in energy levels.
  6. Electron
    A negatively charged particle within the atom.
  7. Energy level

  9. Halogens
    Any of the elements occupying group 17 of the periodic table.
  10. Isotope

  11. Mass number
    The sum of of the number of protons and neutrons in the nucleus.
  12. Metal
    Typically an element that is hard, shiny, malleable,and ductile, and is a good conductor of heat and light.
  13. Metalloid
    An element that shares some properties with metals and some properties of non-metals.
  14. Nucleus
    In chemistry, the positively charged centre of an atom.
  15. Neutron
    An uncharged particle that is part of almost every atomic nucleus.
  16. Non-metal
    Typically, an element that is not hard, shiny, malleable,and ductile, and is a poor conductor of heat and light.
  17. Noble gases
    Any of the gaseous elements occupying Group 18 of the periodic table.
  18. Proton
    A positively charged particle that is part of every atomic nucleus.
  19. Periodic table
    A system for organizing the elements into columns and rows, so that elements with similar properties are in the same column.
  20. Period
    A horizontal row of elements in the periodic table.
  21. Subatomic particle
    A particle that smaller than the atom.
  22. Valence electron
    An electron in the outermost occupied energy level of an atom.
