Periodic Table Groups by Josie O'Connell https://padlet.com/josiegesualda/m7fqwlibe7v3gvgc en-us 2021-10-19 07:17:05 UTC 2024-05-27 05:00:36 UTC hello@padlet.com https://padlet.net/icons/png/2697.png Instructions josiegesualda https://padlet.com/josiegesualda/m7fqwlibe7v3gvgc/wish/1826376892 Each group will be assigned a particular group/family of elements to research. 

The groups will either present their research to the rest of the class or create posts in a class padlet.  Use the guided questions given for each group of elements below. Some of the research you will need to include are listed below:
  • Properties – list two physical and one chemical property the elements in your group share
  • Record the number of valence electron/s the elements in your group have
  • Write down what type of ions the elements in your group form when they react with substances
  • List three examples of elements which belong to each group
  • Write down the balanced formula equations of chemical reactions involving some of these elements (groups 1 and 17 only)
  • Three interesting facts relevant to your group of elements
