Slide 2 - Poll

  • describe the Periodic Table as an arrangement of elements in periods and groups and in order of increasing proton number / atomic number
  • describe the change from metallic to non-metallic character across a period
  • describe the relationship between group number and the charge of the ions formed from elements in that group

Slide 3 - Tekstslide

  • explain similarities in the chemical properties of elements in the same group of the Periodic Table in terms of their electronic configuration  
  • explain how the position of an element in the Periodic Table can be used to predict its properties  
  • identify trends in groups, given information about the elements

Processing

  • Over 100 chemical elements = isolated and identified
  • Each element has one proton more than the previous.
  • This is done so that elements end up in columns with other elements which have similar properties.
  • Elements are arranged on the periodic table in order of increasing atomic number.
  • Vertical columns = groups 
  • Rows = periods

  • Valency (or combining power)  ‚ÄĒ tells you how many bonds an atom can make with another atom or how many electrons its atoms lose, gain or share, to form a compound

Metallic character of the elements:
  • decreases as you move from left to right across a Period
  • increases as you move down a Group
Reason for the trend:
  • due to atoms more readily accepting electrons to fill their valence shells rather than losing them to have the previous, already full, electron shell as their outer shell

  •  Electronic configuration ‚ÄĒ  arrangement of electrons into shells for an atom (e.g., the electronic configuration of carbon is 2, 4)

  • The number of notations = number of occupied shells of electrons the atom has, showing the period
  • The last notation = number of outer electrons the atom has, showing the group number

  •  Elements in the same group ‚ÄĒ  similar chemical properties due to the same number of outermost electrons

  • When atoms collide and react, it is the outermost electrons that interact.

Slide 27 - Tekstslide

  • Lithium and Sodium are in Group I. Do they have the same chemical properties? Explain in terms of the number of outermost electrons, how they react with Group VII elements to form ionic compounds.
