Concepts:
– halogen, diatomic,
energetic stability, valence electrons,
–Reaction, displacement reaction, halide ion
Skills:
–Describe and explain their
trend in color, state, and reactivity with other halide ions
–Predict properties of other
elements in the group given data where appropriate
–Identify uses for each halogen
–Describe and explain the change in reactivity of non-metals
in period 3.
–Identify trends in other non-metal groups given
information about the elements concerned
