Trends and Displacements of halide ions and halogens

Question 1

What is the trend in boiling point down the group

Answer 1

an increase in boiling point due to the increased amount of electrons down the group causing stronger Van Der Waal forces.

Question 2

What is the trend in electonegativity down the group.

Answer 2

the electronegativity will decrease down the group because the most electronegative are at the top right of the table.
