Under standard conditions: Fluorine?
1) Physical state?
2) Colour?
3) This is?
1) Gaseous.
2) Pale yellow.
3) Highly reactive.
2) Green.
3) Poisonous in high concentrations.
1) Liquid.
2) Red.
3) It gives off brown poisonous fumes.
Under standard conditions: Iodine?
1) Solid/Gas.
2) Shiny grey solid, purple gas.
3) The solid will sublime to a gas.
The melting points:
Increase down the group due to increases number of electrons (electron shells) which means there are greater VDW forces of attraction between molecules which require more energy to be broken.
The atomic radius:
Increases down the group due to more electron shells and repulsion between them.
The electronegativity:
Decreases down the group because as the size increases the distance between the outer electrons and the protons in the nucleus increases, thus weakening the electrostatic forces of attraction.
Colours of the Halide ions:
1) Chloride?
2) Bromide?
3) Iodide?
1) Colourless solution.
2) Yellow Solution.
3) Brown Solution.
