Reorder the following (least to most reactive)

• Rb

• Li

• K

• Cs

• Na

All alkali metals have ​ (a)   electron in their ​ (b)   shell. The reactivity ​ (c)   down the group as the number of ​ (d)   increases so the pull from the nucleus is ​ (e)  

• 1
• outer
• increases
• shells
• weaker
• 7
• inner
• neutrons
• decreases
• stronger

Match the following

• Na

• Sodium

• Rb

• Potassium

• K

• Rubidium

• Fr

• Francium

• Li

• Lithium

Alkali metals should not be added directly to acid because

• it is explosive

• they are too expensive

• it would dissolve the glass

• it would produce a bright flash
