20. Element Groups & Properties Name Alkali Metals Alkaline Earth Metals Transition metals Halogens Noble Gases

21. Ordering Elements by Properties Follow the instructions on the small card Arrange the elements based on properties Put elements into columns and rows in a pattern Use physical and chemical properties Why did you put an element card at the top of a column? Why should another be placed lower or to the right?

22. Results? Analyze your results: Make a table that shows the order of your elements (see next slide) Show the patterns for the properties Physical properties - explain the pattern for each physical property Chemical properties – explain the pattern

23. Ordering Groups of Elements by Properties GroupPhysical properties Chemical properties
