• identify trends in groups, given information about the elements  
• describe the Group I alkali metals, lithium, sodium, and potassium, as relatively soft metals with general trends down the group, limited to:
• (a) decreasing melting point
• (b) increasing density
• (c) increasing reactivity  
• predict the properties of other elements in Group I, given information about the elements  

I intend to:
