Atomic Structure

AtomicStructureAtomic Structure

This CELL provides students the opportunity to investigate what makes each element different and how the groupings of the Periodic Table denote chemical and physical properties of the elements. Students also investigate how elements combine together to form compounds.

Investigation focus:

  • Understand that elements are categorized by group and period in the Periodic Table.
  • Understand that elements that share the same physical and chemical properties are categorized in the same groups in the Periodic Table.
  • Recognize the periodic change in chemical and physical properties of the elements as illustrated in the Periodic Table.
  • Investigate the relative solubilities of Group 1 and transition metal ionic compounds.
  • Better understand the reactivity of metals and how to use the Periodic Table to predict the reactivity of metals.
  • Conclude that with elements classified as metals, those located further to the left and top of the Periodic Table are generally more reactive than those further to the right or at the bottom of the Periodic Table.
  • Observe the reactivity levels of non-metals.
  • Understand that elements give up and take electrons in order to complete reactions.
  • Recognize that ionic compounds consist of a metal ion(s) and a nonmetal ion(s).
  • Recognize that organic compounds minimally consist of carbon and hydrogen atoms and often oxygen, sulfur and phosphorous atoms.
