Concepts:
–Group 1, alkali metal, halogen,
melting point, boiling point, trend (pattern)
–reaction, displacement, reactivity, acidic, basic,
metallic, nonmetallic
Skills:
–Describe and explain trends for group 1 and 2 in their
appearance, melting
point, density, and their reaction with water
–Predict properties of other
elements in the group given data where appropriate
–Identify and describe displacement reactions between metals
and water
–Describe and explain the change in reactivity of metals in
period 3 (sodium, magnesium and
aluminum).
